Students often need to be able to compare fractions. Do you know which is bigger between 
and 
?
means the whole has been divided into 5 equal pieces and you have one of them.
means the whole has been divided into 6 equal pieces and you have one of them.
The fraction wall shows that the larger the denominator, the smaller each piece becomes, so is greater than .
Try this exercise to choose the biggest fraction.
Can you interpret the graphs correctly?
Numbers are often rounded to find approximate percentages. For example if 28 out of 119 ESOL students come from Eastern Europe we could round to the nearest ten, giving us 30 out of 120.
30รท120 x 100 = 25% so we can say that 28 out of 119 students is roughly 25%.
Practice approximating percentages with this quiz.
Sometimes complicated fractions can be rounded and cancelled down.
could round to 
because 72 is 70 to the nearest 10 and 99 is 100 to the nearest 10.
See if you can approximate these fractions.

To complete this quiz you need to be able to order decimals. Here is an example to help you.
Which is bigger, 0.3 or 0.25?
Ever so many people make the mistake of saying 0.25 is bigger because 25 is bigger than 3. This is very wrong!
Remember the place value of decimals.
0.3 means three tenths.
0.25 means 2 tenths and 5 hundredths.
Three tenths is bigger than 2 tenths, so 0.3 is bigger.
