Solve 11/2div21/2

$$1 \frac { 1 } { 2 } \div 2 \frac { 1 } { 2 }$$

Evaluate

$$\frac{3}{5}=0.6$$

Solution Steps

Divide \frac{1\times 2+1}{2} by \frac{2\times 2+1}{2} by multiplying \frac{1\times 2+1}{2} by the reciprocal of \frac{2\times 2+1}{2}.

$$\frac{\left(1\times 2+1\right)\times 2}{2\left(2\times 2+1\right)}$$

Cancel out 2 in both numerator and denominator.

$$\frac{1+2}{1+2\times 2}$$

Add 1 and 2 to get 3.

$$\frac{3}{1+2\times 2}$$

Multiply 2 and 2 to get 4.

$$\frac{3}{1+4}$$

Add 1 and 4 to get 5.

$$\frac{3}{5}$$

Factor

$$\frac{3}{5} = 0.6$$
