Can you remember what to do here? If we look at the number after the decimal point, as this is higher than a 5, we round up to the next whole number which is 9.
  • Question 2

Round the following number to the nearest whole number.

1.76 =
 
CORRECT ANSWER
2
EDDIE SAYS
Remember what we need to do? If we look at the number after the decimal point, as this is higher than a 5, we round up to the next whole number which is 2.
  • Question 3

Round the following number to the nearest whole number.

1.96 =
 
CORRECT ANSWER
2
EDDIE SAYS

Round the following number to the nearest whole number.

3.21 =
 
CORRECT ANSWER
3
EDDIE SAYS

  • Question 11

Read the question carefully!

 

Round the following number to 1 decimal place.

4.09 =
 
CORRECT ANSWER
4.1
EDDIE SAYS
It said round the answer to one decimal place. So, now we look to the second number after the decimal point, if it is above 5 we round up and if it is below 5 we move down. The 9 is above 5, so we round this number from 4.09 to one decimal place and get 4.1.
  • Question 12

Round the following number to 1 decimal place.

4.67 =
 
CORRECT ANSWER
4.7
EDDIE SAYS
Remember what to do? It said round the answer to one decimal place. So, now we look to the second number after the decimal point, if it is above 5 we round up and if it is below 5 we move down. The 7 is above 5, so we round this number from 4.67 to one decimal place and get 4.7.
  • Question 13

Round the following number to 1 decimal place.

4.64 =
 
CORRECT ANSWER
4.6
EDDIE SAYS
It said round the answer to one decimal place. So, now we look to the second number after the decimal point, if it is above 5 we round up and if it is below 5 we move down. The 4 is below 5, so this time we round this number down from 4.64 to one decimal place and get 4.6.
  • Question 14

Round the following number to 1 decimal place.

2.92 =
 
CORRECT ANSWER
2.9

2.97 =
 
CORRECT ANSWER
3
3.0
