7-100.

Find the missing value in each of the pairs of equivalent ratios below.

1. $\frac{x}{10}=\frac{6}{15}$

Think about what values would go in a Giant One to turn tenths into fifteenths.

$\left(\frac{x}{10}\right)\left(\frac{1.5}{1.5}\right)=\frac{6}{15}$

$x(1.5)=6$
What number multiplied by $1.5$ gives $6$?

$x=4$

1. $\frac{12}{9}=\frac{8}{x}$

This problem is very similar to part (a).

$x=6$

1. $\frac{16}{38}=\frac{200}{m}$

How could you use a Giant One to find the value of $m$?
