$$(990-330) \div 110+(645+387-512) \div 129$$

Evaluate

$$\frac{1294}{129}\approx 10.031007752$$

Solution Steps

Subtract 330 from 990 to get 660.

$$\frac{660}{110}+\frac{645+387-512}{129}$$

Divide 660 by 110 to get 6.

$$6+\frac{645+387-512}{129}$$

Add 645 and 387 to get 1032.

$$6+\frac{1032-512}{129}$$

Subtract 512 from 1032 to get 520.

$$6+\frac{520}{129}$$

Convert 6 to fraction \frac{774}{129}.

$$\frac{774}{129}+\frac{520}{129}$$

Since \frac{774}{129} and \frac{520}{129} have the same denominator, add them by adding their numerators.

$$\frac{774+520}{129}$$

Add 774 and 520 to get 1294.

$$\frac{1294}{129}$$

Factor

$$\frac{2 \cdot 647}{3 \cdot 43} = 10\frac{4}{129} = 10.031007751937985$$
