Answer:

Explanation on ratio and rates.

Step-by-step explanation:

So rates are when you compare two things. For example let's say there are 12 boys and 10 girls. The ratio would be 12:10 or 6:5. Rates is also comparing two things but in fraction format. For example if you drive 30 miles in 3 hours the rate would be 30/3. 10 miles per hour is a unit rate since it is 1 hour, 10/1. I hope this helps you, have a good day.

Answer:

Step-by-step explanation:

Given: Paula and Kawai shared $\$312$ in the ratio of $6:7$ .

To find: How much money did each person get?

$6x+7x=312$

$\implies13x=312$

$\implies x=\frac{312}{13} =24$

Therefore, Paula get $6\times 24=\$144$ , and Kawai get $7\times 24=\$168$ .

Hence, Paula get $\$144$ and Kawai get $\$168$ .
