Week 4 Hypatias

Preparations for the Mathathon have shown that some of you are a little confused around fractions and finding fractions of numbers.
To find fractions out we 

Fractions

A fraction is part of an entire object.

	1 4	One fourth is yellow
	2 4	Two fourths are yellow. One half is yellow.
	3 4	Three fourths are yellow.
	4 4	Four fourths are yellow.

 As happy as that diagram is, with all of its happy bright cheerful colours, it doesn't necessarily help us when trying to solve 1/4 of 16.

So lets start at the beginning.
4/4=1/1= 1. 

4/4 is a fraction, but it is also a whole number. 
Because 4  ÷ 4 = 1 

If we 
were to start breaking up 4/4 into parts of 16 a quarter of sixteen is 4, a half of sixteen is 8, three quarters of sixteen is 12, and four quarters of 16 is 16.

Okay, so for a start in your books write the yellow stuff in your books and then work out

1/2 of 36.
1/4 of 20.
1/5 of 25.
3/5 of 25.

If you feel confident with this, move onto the next questions.
