Solve 9div11/2+5div1.25

$$9 \div 1 \frac{ 1 }{ 2 } +5 \div 1.25$$

Evaluate

$$10$$

Solution Steps

Divide 9 by \frac{1\times 2+1}{2} by multiplying 9 by the reciprocal of \frac{1\times 2+1}{2}.

$$\frac{9\times 2}{1\times 2+1}+\frac{5}{1.25}$$

Multiply 9 and 2 to get 18.

$$\frac{18}{1\times 2+1}+\frac{5}{1.25}$$

Multiply 1 and 2 to get 2.

$$\frac{18}{2+1}+\frac{5}{1.25}$$

Add 2 and 1 to get 3.

$$\frac{18}{3}+\frac{5}{1.25}$$

Divide 18 by 3 to get 6.

$$6+\frac{5}{1.25}$$

Expand \frac{5}{1.25} by multiplying both numerator and the denominator by 100.

$$6+\frac{500}{125}$$

Divide 500 by 125 to get 4.

$$6+4$$

Add 6 and 4 to get 10.

$$10$$

Factor

$$2\times 5$$
