Solve 31/2+4/1

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

Evaluate

$$\frac{15}{2}=7.5$$

Solution Steps

Multiply 3 and 2 to get 6.

$$\frac{6+1}{2}+\frac{4}{1}$$

Add 6 and 1 to get 7.

$$\frac{7}{2}+\frac{4}{1}$$

Anything divided by one gives itself.

$$\frac{7}{2}+4$$

Convert 4 to fraction \frac{8}{2}.

$$\frac{7}{2}+\frac{8}{2}$$

Since \frac{7}{2} and \frac{8}{2} have the same denominator, add them by adding their numerators.

$$\frac{7+8}{2}$$

Add 7 and 8 to get 15.

$$\frac{15}{2}$$

Factor

$$\frac{3 \cdot 5}{2} = 7\frac{1}{2} = 7.5$$
