Solve 12000*1/10+7500*7/10+3000*1/5

$$12000 \times \frac{ 1 }{ 10 } +7500 \times \frac{ 7 }{ 10 } +3000 \times \frac{ 1 }{ 5 }$$

Evaluate

$$7050$$

Solution Steps

Multiply 12000 and \frac{1}{10} to get \frac{12000}{10}.

$$\frac{12000}{10}+7500\times \frac{7}{10}+3000\times \frac{1}{5}$$

Divide 12000 by 10 to get 1200.

$$1200+7500\times \frac{7}{10}+3000\times \frac{1}{5}$$

Express 7500\times \frac{7}{10} as a single fraction.

$$1200+\frac{7500\times 7}{10}+3000\times \frac{1}{5}$$

Multiply 7500 and 7 to get 52500.

$$1200+\frac{52500}{10}+3000\times \frac{1}{5}$$

Divide 52500 by 10 to get 5250.

$$1200+5250+3000\times \frac{1}{5}$$

Add 1200 and 5250 to get 6450.

$$6450+3000\times \frac{1}{5}$$

Multiply 3000 and \frac{1}{5} to get \frac{3000}{5}.

$$6450+\frac{3000}{5}$$

Divide 3000 by 5 to get 600.

$$6450+600$$

Add 6450 and 600 to get 7050.

$$7050$$
