proportion- an equation which states that two ratios (fractions) are equal
rate- a comparison of two quantities measured in different units
55 mphratio- a comparison of quantities that have the same units
Task 2:
÷ 5
miles 360 72
_____ ______ = _______
hours 5 1
÷ 5
5 hours to travel 360 miles is about 72 mph.
2) As a playgroup worker, if I increase the amount of apple juice I am serving at the playgroup from 25 ml to 100 ml, how much should I increase the the orange juice to, to keep the quantities in the same proportion? The orange juice is 50 ml to start with.
apple 25 ml 100 ml
_______ _______ = _________
hours 50 ml 200 ml
The playgroup worker should increase the orange juice quantity to 200ml to keep it in proportion.

Task 5
1. No, this is not fair
x 30 000 000
2. $ 100 $ 3 000 000 000
______ = _______________
15 years 450 000 000 years
x 30 000 000
If the judge used proportional reasoning, then the CEO should get 450 million years in prison to be fair. That's why I don't think this is fair.
