Solve 11/2+2/5=13/4

$$1 \frac { 1 } { 2 } + \frac { 2 } { 5 } = 1 \frac { 3 } { 4 }$$

Verify

Solution Steps

Multiply both sides of the equation by 20, the least common multiple of 2,5,4.

$$10\left(1\times 2+1\right)+8=5\left(1\times 4+3\right)$$

Multiply 1 and 2 to get 2.

$$10\left(2+1\right)+8=5\left(1\times 4+3\right)$$

Add 2 and 1 to get 3.

$$10\times 3+8=5\left(1\times 4+3\right)$$

Multiply 10 and 3 to get 30.

$$30+8=5\left(1\times 4+3\right)$$

Add 30 and 8 to get 38.

$$38=5\left(1\times 4+3\right)$$

Multiply 1 and 4 to get 4.

$$38=5\left(4+3\right)$$

Add 4 and 3 to get 7.

$$38=5\times 7$$

Multiply 5 and 7 to get 35.

$$38=35$$

Compare 38 and 35.

$$\text{false}$$
