Converting between decimals and fractions
Thanks to John Ford for this quiz.
You need to be able to convert fractions to decimals and decimals to fractions.
To convert a fraction to a decimal divide the numerator (top number) by the denominator (bottom number).
eg 3/4
3÷4 = 0.75
To change a decimal to a fraction think what place value the number on the right hand side has.
eg 0.45
The 5 is in the hundredths column, so the denominator will be 100.
The numerator is 45
So 0.45 = 45/100
This cancels down as both numbers divide by 5.
45/100 = 9/20
es best!
