Question

$$\frac { 2 a - 3 } { 5 } \frac { 7 } { 8 }$$

Evaluate

$\frac{7a}{20}-\frac{21}{40}$

Solution Steps

Multiply $\frac{2a-3}{5}$ times $\frac{7}{8}$ by multiplying numerator times numerator and denominator times denominator.

$$\frac{\left(2a-3\right)\times 7}{5\times 8}$$

Multiply $5$ and $8$ to get $40$.

$$\frac{\left(2a-3\right)\times 7}{40}$$

Use the distributive property to multiply $2a-3$ by $7$.

$$\frac{14a-21}{40}$$

Expand

$\frac{7a}{20}-\frac{21}{40}$

Solution Steps

Multiply $\frac{2a-3}{5}$ times $\frac{7}{8}$ by multiplying numerator times numerator and denominator times denominator.

$$\frac{\left(2a-3\right)\times 7}{5\times 8}$$

Multiply $5$ and $8$ to get $40$.

$$\frac{\left(2a-3\right)\times 7}{40}$$

Use the distributive property to multiply $2a-3$ by $7$.

$$\frac{14a-21}{40}$$
