Proportion - States that two ratios are equal.

1. 5 hours to travel 360 miles is about _____mph.

2. As a playgroup worker , if I increase the amount of apple juice I am serving at the playgroup from 25ml to 100 ml, how much should I increase the orange juice to, to keep the quantities in the same proportion? The orange juice is 50 to start with.

Three ways of proving if equivalent ratios are true is:

Answer: 3/4 = 12/16 is true

4/9 = 16/72 is false

1. No it does not seem fair.

2. No its not fair because the man stole $100 and he surrendered it and he go 15 years in jail while the Ex-mortgage stole $3 billion and he got 3 years in jail.

3.I would send the Ex-mortgage CEO 30 years in jail and the man 1 year in jail.
