Solve 31/3-12/3=21/3

$$3 \frac{ 1 }{ 3 } -1 \frac{ 2 }{ 3 } =2 \frac{ 1 }{ 3 }$$

Solution Steps

Multiply both sides of the equation by 3.

$$3\times 3+1-\left(1\times 3+2\right)=2\times 3+1$$

Multiply 3 and 3 to get 9.

$$9+1-\left(1\times 3+2\right)=2\times 3+1$$

Add 9 and 1 to get 10.

$$10-\left(1\times 3+2\right)=2\times 3+1$$

Multiply 1 and 3 to get 3.

$$10-\left(3+2\right)=2\times 3+1$$

Add 3 and 2 to get 5.

$$10-5=2\times 3+1$$

Subtract 5 from 10 to get 5.

$$5=2\times 3+1$$

Multiply 2 and 3 to get 6.

$$5=6+1$$

Add 6 and 1 to get 7.

$$5=7$$

Compare 5 and 7.
