Solve 2/1-38*3/15+8*10/50=4

$$\frac{ 2 }{ 1 } - \frac{ 38 \times 3 }{ 15 } + \frac{ 8 \times 10 }{ 50 } = 4$$

Verify

Solution Steps

Multiply both sides of the equation by 150, the least common multiple of 15,50.

$$150\times 2-10\times 38\times 3+3\times 8\times 10=600$$

Multiply 150 and 2 to get 300.

$$300-10\times 38\times 3+3\times 8\times 10=600$$

Multiply -10 and 38 to get -380.

$$300-380\times 3+3\times 8\times 10=600$$

Multiply -380 and 3 to get -1140.

$$300-1140+3\times 8\times 10=600$$

Subtract 1140 from 300 to get -840.

$$-840+3\times 8\times 10=600$$

Multiply 3 and 8 to get 24.

$$-840+24\times 10=600$$

Multiply 24 and 10 to get 240.

$$-840+240=600$$

Add -840 and 240 to get -600.

$$-600=600$$

Compare -600 and 600.

$$\text{false}$$
