11-Plus Maths Quiz - Decimal Numbers 3 (Easy) (Questions)

Welcome to the third in our Easy section of Eleven Plus maths quizzes on decimal numbers. In it we look in particular at the value of those digits placed after the decimal point. You know that, in whole numbers, the columns read right to left are for units, tens, hundreds, thousands etc. Well. In decimal numbers, it’s almost the same, but with no ‘units’ column - and in reverse!

Perhaps this will help make it clearer:

The fractions get smaller and smaller as you read left to right.

Have a go at this quiz and see how well you understand decimals. Once you get all questions right first time, why not move on to our next quiz for more of a challenge!

11-Plus Maths Quiz - Decimal Numbers 3 (Easy) (Answers)
1. Which digit in the number below is the same as 10 thousandths?
98,765.312
[x] The one
[ ] The nine
[ ] The two
[ ] The eight
10 thousandths are the same as one-hundredth, and would be shown in decimal as 0.01
2. What is three-thirds represented as a decimal number?
[ ] 0.999
[x] 1
[ ] 3.333
[ ] 0.666
Three-thirds make one!
If all the numbers after the decimal point are zeros, then you can leave them out
3. What is two-thirds represented as a decimal number?
[ ] 0.666
[ ] 0.6
[x] 0.667
[ ] 0.66
One-third as a decimal is 0.333... so two-thirds is 0.333... + 0.333... = 0.666... which we round up to 0.667
4. What is one-third represented as a decimal number?
[ ] 0.3
[ ] 0.4
[ ] 0.25
[x] 0.333
One-third as a decimal is 1 ÷ 3 = 0.333… the threes are recurring, which means they go on forever!
5. What is the value of the 2 in the number 101.942?
[x] 2 thousandths
[ ] 2 hundredths
[ ] 2 tenths
[ ] 2 ten-thousandths

6. What is the value of the 5 in the number 891.256?
[ ] 5 thousandths
[x] 5 hundredths
[ ] 5 tenths
