Solve {l}{3*30=90(4/8)}{200-90=110(4/4)}

$$\left. \begin{array} { l } { 3 \times 30 = 90 ( \frac { 4 } { 8 } ) } \\ { 200 - 90 = 110 ( \frac { 4 } { 4 } ) } \end{array} \right.$$

Solution Steps

Divide 4 by 4 to get 1.

$$3\times 30=90\times \frac{4}{8}\text{ and }200-90=110\times 1$$

Multiply 3 and 30 to get 90.

$$90=90\times \frac{4}{8}\text{ and }200-90=110\times 1$$

Reduce the fraction \frac{4}{8} to lowest terms by extracting and canceling out 4.

$$90=90\times \frac{1}{2}\text{ and }200-90=110\times 1$$

Multiply 90 and \frac{1}{2} to get \frac{90}{2}.

$$90=\frac{90}{2}\text{ and }200-90=110\times 1$$

Divide 90 by 2 to get 45.

$$90=45\text{ and }200-90=110\times 1$$

Compare 90 and 45.

$$\text{false}\text{ and }200-90=110\times 1$$

Subtract 90 from 200 to get 110.

$$\text{false}\text{ and }110=110\times 1$$

Multiply 110 and 1 to get 110.

$$\text{false}\text{ and }110=110$$

Compare 110 and 110.

$$\text{false}\text{ and }\text{true}$$

The conjunction of \text{false} and \text{true} is \text{false}.

$$\text{false}$$
