Solve 84/7+3*41/7

$$8 \frac{ 4 }{ 7 } +3 \times 4 \frac{ 1 }{ 7 }$$

Evaluate

$$21$$

Solution Steps

Multiply 8 and 7 to get 56.

$$\frac{56+4}{7}+3\times \frac{4\times 7+1}{7}$$

Add 56 and 4 to get 60.

$$\frac{60}{7}+3\times \frac{4\times 7+1}{7}$$

Multiply 4 and 7 to get 28.

$$\frac{60}{7}+3\times \frac{28+1}{7}$$

Add 28 and 1 to get 29.

$$\frac{60}{7}+3\times \frac{29}{7}$$

Express 3\times \frac{29}{7} as a single fraction.

$$\frac{60}{7}+\frac{3\times 29}{7}$$

Multiply 3 and 29 to get 87.

$$\frac{60}{7}+\frac{87}{7}$$

Since \frac{60}{7} and \frac{87}{7} have the same denominator, add them by adding their numerators.

$$\frac{60+87}{7}$$

Add 60 and 87 to get 147.

$$\frac{147}{7}$$

Divide 147 by 7 to get 21.

$$21$$

Factor

$$3\times 7$$
