Solve 34/7*12/5*1.25

$$3 \frac { 4 } { 7 } \times 1 \frac { 2 } { 5 } \times 1.25$$

Evaluate

$$6.25$$

Solution Steps

Multiply 3 and 7 to get 21.

$$\frac{21+4}{7}\times \frac{1\times 5+2}{5}\times 1.25$$

Add 21 and 4 to get 25.

$$\frac{25}{7}\times \frac{1\times 5+2}{5}\times 1.25$$

Multiply 1 and 5 to get 5.

$$\frac{25}{7}\times \frac{5+2}{5}\times 1.25$$

Add 5 and 2 to get 7.

$$\frac{25}{7}\times \frac{7}{5}\times 1.25$$

Multiply \frac{25}{7} times \frac{7}{5} by multiplying numerator times numerator and denominator times denominator.

$$\frac{25\times 7}{7\times 5}\times 1.25$$

Cancel out 7 in both numerator and denominator.

$$\frac{25}{5}\times 1.25$$

Divide 25 by 5 to get 5.

$$5\times 1.25$$

Multiply 5 and 1.25 to get 6.25.

$$6.25$$

Factor

$$\frac{5 ^ {2}}{2 ^ {2}} = 6\frac{1}{4} = 6.25$$
