Simplify each of the following expressions.

1. $12\%$ of $4.2$

Multiply $4.2$ by $0.12$ to find the answer.

$0.504$

1. $\frac { 5 } { 7 } + ( 1 \frac { 2 } { 3 } ) ( \frac { 3 } { 4 } )$

Make sure to multiply before you add the terms.

$1\frac{27}{28}$

1. $10 \frac { 1 } { 4 } \div 0.125$

$0.125$ is equal to $\frac{1}{8}$ and $10$ and one-fourth is equal to $\frac{41}{4}$.
