Worksheet Overview

QUESTION 1 of 10

In this worksheet, you must solve problems using a calculator.

First clear the calculator display.

 

Remember that:

  • the inverse of adding is subtracting 
  • the inverse of multiplying is dividing

 

Also remember that: 

  • 40 ÷ 10 = 4 and 40 ÷ 4 = 10

 

 

Example 1

Write in the missing number.

79.5 × ________ = 773.9

 

Answer

On your calculator, work out the inverse, which is

773.9 ÷ 79.5 = 9.73459119496

So, we write

79.5 × 9.73459119496 = 773.9

 

 

Example 2

Work out

45% of 3404

 

Answer

45% is 45/100 which is 0.45 as a decimal.

So, on the calculator, we work out

0.45 × 3404 = 1531.8

Work out the missing number.

  • Question 3

Work out the missing number.

 

29% of 8892 = _______

CORRECT ANSWER
2578.68
EDDIE SAYS
Remember that 29% is the same as 29/100 or 0.29, so we can then do 8892 × 0.29 to find the answer 2578.68.
  • Question 4

Work out the missing number.

 

69% of 3565 = _______

CORRECT ANSWER
2459.85
EDDIE SAYS
69% is 0.69, so we type 3565 × 0.69 to find the answer 2459.85.
  • Question 5

Work out the missing number.

 

33% of 3779 = _______

CORRECT ANSWER
1247.07
EDDIE SAYS
33% is 0.33, so we can do 3779 × 0.33 to find the answer 1247.07.
  • Question 6

Work out the missing number.

 

71% of 7066 = _______

CORRECT ANSWER
5016.86
EDDIE SAYS
71% is 0.71, so we can do 7066 × 0.71 to find the answer 5016.86.
  • Question 7

Work out what the square root of 64 is, and write it in the box below.

CORRECT ANSWER
8
EDDIE SAYS
Remember, the square root is the number which, when multiplied by itself, gives 64.
In this case, the answer is 8, as 8 × 8 = 64.
  • Question 8

Work out what the square root of 9 is, and write it in the box below.

CORRECT ANSWER
3
EDDIE SAYS
3 × 3 = 9, so the square root of 9 is 3.
  • Question 9

Work out the answer.

 

(74 + 10) ÷ (82 + 70)  =  _______

CORRECT ANSWER
0.5526316
EDDIE SAYS
First, we need to work out the numbers in the brackets.
74 + 10 = 84, and 82 + 70 = 152
We then divide 84 by 152.
So, 84 ÷ 152 = 0.5526316.
  • Question 10

Work out

 

(82 + 13) ÷ (63 + 67)  =  _______

CORRECT ANSWER
0.73076923
EDDIE SAYS
First, we need to work out the numbers in the brackets.
82 + 13 = 95, and 63 + 67 = 130
We then divide 95 by 130.
So, 95 ÷ 130 = 0.73076923.
