Solve Fractions and Multiples Problems Worksheet

In this activity, you will use your knowledge of fractions and multiples to solve a range of problems.

Let's work through one together.

I ate ¼ of a pie and served ⅛ later to my guests.

What fraction was served to my guests?

1st step: Convert

Convert ¼ to eighths so both fractions have the same denominator and then will be easier to work with

¼ both numbers should be multiplied by 2 to convert to eighths as 4 x 2 = 8

So I ate and I saved ⅛ a total of ⅜

2nd step: Subtract

The total pie was originally a whole =

So ⅝ of the pie was served to guests

Last year, Miss Smith weighed 60 kg.

This year she weighs 2/5 more.

How much does Miss Smith weigh this year?

ANSWERS

Question 1

James has a bag of marbles.

There were 56 in the bag.

He gave away &frac38; of them.

How many are left?

Marbles

CORRECT ANSWER

EDDIE SAYS

First, we need to find 1/8 of 56 56 ÷ 8 = 7 1/8 = 7 Then 7 x 3 to find 3/8 = 21 56 - 21 = 35 Therefore there are 35 marbles left

ANSWERS

Question 2

In a pet shop, 3/12 of the pets are fish and 1/6 are rabbits.

Which type of pet is there more of?

CORRECT ANSWER

Fish

EDDIE SAYS

To find the answer to this fraction problem, we needed to convert both fractions to a common denominator. We can convert 1/6 into 12ths 1/6 = 2/12 So, 3/12 of the pets are fish and 2/12 pets are rabbits. Therefore, there are more fish than rabbits.

ANSWERS

Question 3

Sam has an amazing collection of stickers.

He gives 2/5 to his sister and 3/8 to his best friend.

Who does he give the most stickers to?

CORRECT ANSWER

EDDIE SAYS

To solve this type of fraction problem, we need to ensure both fractions have a common denominator by finding the lowest common multiple. The lowest common multiple of 5 and 8 is 40. 2/5 = 16/40 3/8= 15/40 Therefore, Sam gave his sister the most stickers.

ANSWERS

Question 4

Two contestants are competing in a grape eating challenge.

Rich has eaten and Sally has gobbled ⅝ of hers.

Who is currently leading the contest?

Write the name in the box.

CORRECT ANSWER

Rich
rich

EDDIE SAYS

How did you find this one? To directly compare the fractions, we needed to find the common denominator by using the lowest common multiple. The lowest common multiple of 10 and 8 is 80. 7/10 = 56/80 5/8 = 50/80 Therefore, Rich is currently leading the contest.

ANSWERS

Question 5

Lucy and Max have identical cars.

Lucy has used of the petrol in her car.

Max has used of the fuel in his.

Who has more fuel left in their car?

CORRECT ANSWER

Lucy
lucy

EDDIE SAYS

Again, in order to directly compare the fractions, we need to find the common denominator by using the lowest common multiple. The lowest common multiple of 7 and 9 is 63. 4/7 = 36 /63 7/9 = 49/63 Max has used the most fuel, therefore, Lucy has the most fuel left in her car.

ANSWERS

Question 6

Kim and Tom swam in a swimming gala.

Kim swam ⅝ of a mile.

Tom swam ⅔ of a mile.

Can you match each fraction to its equivalent?

This will then clearly show you who has swum the furthest.

Indoor swimming pool

CORRECT ANSWER

Column A	Column B
Swam furthest distance	Tom
Swam smaller distance	Kim
5 ⁄8	15 ⁄24
2 ⁄3	16 ⁄24

EDDIE SAYS

5/8 = 15/24 2/3 = 16/24 Therefore, Tom swam furthest and Kim swam the lesser distance. Are you feeling more confident? Your focus is great, four more questions to go...

ANSWERS

Question 7

Dad gave his two children the same amount of pocket money.

Alisha spent ⅚ on a new top.

Jez spent on a game.

Can you match each fraction to its equivalent?

This will then clearly show you who has the most pocket money remaining.

CORRECT ANSWER

Column A	Column B
Spent most pocket money	Alisha
Spent least pocket money	Jez
5 ⁄6	45 ⁄54
7 ⁄9	42 ⁄54

EDDIE SAYS

5/6 = 45/54 7/9 = 42/54 You can now see, Alisha has spent the most pocket money.

ANSWERS

Question 8

Karina took 5/12 of the sweets and Ivy took 3/8 of the sweets.

What fraction of the sweets did they take between them?

Write your answer as a fraction, use a '/' and do not leave a space between numbers.

CORRECT ANSWER

19/24

EDDIE SAYS

To solve this problem, we need to first convert the fractions into the same denominator by using the lowest common multiple. The lowest common multiple of 12 and 8 is 24. 5/12= 10/24 3/8 = 9/24 By adding both of the fractions together, we then know that Karina and Ivy took a total of 19/24 of the sweets. You’re making great progress!

ANSWERS

Question 9

Someone has snuck into the kitchen and eaten 3/10 of John's cake.

He had already eaten 1/2 himself.

How much cake is still left?

Chocolate cake

CORRECT ANSWER

EDDIE SAYS

To solve this problem, we first need to convert the fractions into the same denominator by using the lowest common multiple. The lowest common multiple of 10 and 2 is 5 The person that snuck into the kitchen has eaten 3/10 and John has eaten 5/10 which means in total 8/10 of the cake has been eaten. There are 2/10 of the cake left, which can be simplified to be 1/5 of the cake remaining. Poor John!

ANSWERS

Question 10

Last year, Miss Smith weighed 60 kg.

This year she weighs 2/5 more.

How much does Miss Smith weigh this year?

CORRECT ANSWER

EDDIE SAYS

To find out Miss Smith's weight, we firstly needed to find 1/5 of 60. 60 ÷ 5 = 12 1/5 = 12 2/5 = 24 So, 60 + 24 = 84 kg Great work, you've completed another activity! How about attempting another one so you feel super confident?
