Solve 42/5*12/3

$$4 \frac { 2 } { 5 } \times 1 \frac { 2 } { 3 }$$

Evaluate

$$\frac{22}{3}\approx 7.333333333$$

Solution Steps

Multiply 4 and 5 to get 20.

$$\frac{20+2}{5}\times \frac{1\times 3+2}{3}$$

Add 20 and 2 to get 22.

$$\frac{22}{5}\times \frac{1\times 3+2}{3}$$

Multiply 1 and 3 to get 3.

$$\frac{22}{5}\times \frac{3+2}{3}$$

Add 3 and 2 to get 5.

$$\frac{22}{5}\times \frac{5}{3}$$

Multiply \frac{22}{5} times \frac{5}{3} by multiplying numerator times numerator and denominator times denominator.

$$\frac{22\times 5}{5\times 3}$$

Cancel out 5 in both numerator and denominator.

$$\frac{22}{3}$$

Factor

$$\frac{2 \cdot 11}{3} = 7\frac{1}{3} = 7.333333333333333$$
