Solving Maths Problem's (Segments)

L.I- WALT find simple fractions of shapes and lengths.

Problem: Mum bought these lolly snakes. She shared each one equally among her five children. 

How many segments did each get?

I know the answer is 20 because......

One fifth of 100 = 20, I know the answer is 100 because 20 + 20 = 40 and another 20 + 20 = 40, so 40 + 40 = 80, and 80 + 20 = 100, another way is 100 divided by 5 = 20 and 5 x 20 =100
