Solve 9*(12.5-4)(1+1/2)

$$9 \times (12.5-4)(1+ \frac{ 1 }{ 2 } )$$

Evaluate

$$114.75$$

Solution Steps

Subtract 4 from 12.5 to get 8.5.

$$9\times 8.5\left(1+\frac{1}{2}\right)$$

Multiply 9 and 8.5 to get 76.5.

$$76.5\left(1+\frac{1}{2}\right)$$

Convert 1 to fraction \frac{2}{2}.

$$76.5\left(\frac{2}{2}+\frac{1}{2}\right)$$

Since \frac{2}{2} and \frac{1}{2} have the same denominator, add them by adding their numerators.

$$76.5\times \frac{2+1}{2}$$

Add 2 and 1 to get 3.

$$76.5\times \frac{3}{2}$$

Convert decimal number 76.5 to fraction \frac{765}{10}. Reduce the fraction \frac{765}{10} to lowest terms by extracting and canceling out 5.

$$\frac{153}{2}\times \frac{3}{2}$$

Multiply \frac{153}{2} times \frac{3}{2} by multiplying numerator times numerator and denominator times denominator.

$$\frac{153\times 3}{2\times 2}$$

Do the multiplications in the fraction \frac{153\times 3}{2\times 2}.

$$\frac{459}{4}$$

Factor

$$\frac{17 \cdot 3 ^ {3}}{2 ^ {2}} = 114\frac{3}{4} = 114.75$$
