Solve 7/5+1/2*3/2

$$\frac { 7 } { 5 } + \frac { 1 } { 2 } \cdot \frac { 3 } { 2 }$$

Evaluate

$$\frac{43}{20}=2.15$$

Solution Steps

Multiply \frac{1}{2} times \frac{3}{2} by multiplying numerator times numerator and denominator times denominator.

$$\frac{7}{5}+\frac{1\times 3}{2\times 2}$$

Do the multiplications in the fraction \frac{1\times 3}{2\times 2}.

$$\frac{7}{5}+\frac{3}{4}$$

Least common multiple of 5 and 4 is 20. Convert \frac{7}{5} and \frac{3}{4} to fractions with denominator 20.

$$\frac{28}{20}+\frac{15}{20}$$

Since \frac{28}{20} and \frac{15}{20} have the same denominator, add them by adding their numerators.

$$\frac{28+15}{20}$$

Add 28 and 15 to get 43.

$$\frac{43}{20}$$

Factor

$$\frac{43}{2 ^ {2} \cdot 5} = 2\frac{3}{20} = 2.15$$
