This is the second of our easy quizzes on decimal numbers. It may sound complicated, but the word ‘decimal’ simply means using tenths, hundredths, thousandths etc. to represent fractions. Tens, hundreds and thousands are shown before the decimal point, whilst tenths, hundredths and thousandths are shown after it.
Decimal numbers are easy, once you get the hang of them! Let’s take some fractions: a half, a quarter and a third. To represent these as decimals, simply divide the number at the top of the fraction by the number at the bottom. So, a half = 1 ÷ 2 = 0.5, a quarter = 1 ÷ 4 = 0.25 and a third = 1 ÷ 3 = 0.333.
Once you’ve mastered this quiz, and the other easy ones on decimal numbers, then why not move up a level to our medium quizzes? The more you practice using decimals, the sooner you will be confident with them.














Decimal numbers are in columns just like ordinary numbers  but backwards! Thousands, hundreds, tens, units, tenths, hundredths, thousandths

There is no 'units' column after the decimal point  it's tenths first, then hundredths, thousandths etc.


TIP:
The first number to the right of the dp is in the tenths place position, e.g. 0 in 756.098 The second number to the right of the dp is in the hundredths place position, e.g. 9 in 756.098 The third number to the right of the dp is in the thousandths place position, e.g. 8 in 756.098 
100 ÷ 4 = 25, so 1 ÷ 4 = 0.25


Decimal numbers are in columns just like ordinary numbers  but backwards! Thousands, hundreds, tens, units, tenths, hundredths, thousandths

There is no 'units' column after the decimal point  it's tenths first, then hundredths, thousandths etc. But the 4 in 234.567 comes before the dp.


Twoquarters = onehalf. Onehalf as a decimal is 1 ÷ 2 = 0.5

TIP:
The first number to the right of the dp is in the tenths place position, e.g. 6 in 987.654 The second number to the right of the dp is in the hundredths place position, e.g. 5 in 987.654 The third number to the right of the dp is in the thousandths place position, e.g. 4 in 987.654 

Ten thousandths are the same as onehundredth, and would be shown in decimal as 0.01

Onequarter is 0.25 so threequarters is 0.25 + 0.25 + 0.25 = 0.75
