Solve 72/3-27/8=4

$$7 \frac { 2 } { 3 } - 2 \frac { 7 } { 8 } = 4$$

Verify

Solution Steps

Multiply both sides of the equation by 24, the least common multiple of 3,8.

$$8\left(7\times 3+2\right)-3\left(2\times 8+7\right)=96$$

Multiply 7 and 3 to get 21.

$$8\left(21+2\right)-3\left(2\times 8+7\right)=96$$

Add 21 and 2 to get 23.

$$8\times 23-3\left(2\times 8+7\right)=96$$

Multiply 8 and 23 to get 184.

$$184-3\left(2\times 8+7\right)=96$$

Multiply 2 and 8 to get 16.

$$184-3\left(16+7\right)=96$$

Add 16 and 7 to get 23.

$$184-3\times 23=96$$

Multiply -3 and 23 to get -69.

$$184-69=96$$

Subtract 69 from 184 to get 115.

$$115=96$$

Compare 115 and 96.

$$\text{false}$$
