Solve 12left(3+1/2right)div1*30+0*70

$$12 \left( 3+ \frac{ 1 }{ 2 } \right) \div 1 \cdot 30+0 \cdot 70$$

Evaluate

$$1260$$

Solution Steps

Convert 3 to fraction \frac{6}{2}.

$$\frac{12\left(\frac{6}{2}+\frac{1}{2}\right)}{1}\times 30+0\times 70$$

Since \frac{6}{2} and \frac{1}{2} have the same denominator, add them by adding their numerators.

$$\frac{12\times \frac{6+1}{2}}{1}\times 30+0\times 70$$

Add 6 and 1 to get 7.

$$\frac{12\times \frac{7}{2}}{1}\times 30+0\times 70$$

Express 12\times \frac{7}{2} as a single fraction.

$$\frac{\frac{12\times 7}{2}}{1}\times 30+0\times 70$$

Multiply 12 and 7 to get 84.

$$\frac{\frac{84}{2}}{1}\times 30+0\times 70$$

Divide 84 by 2 to get 42.

$$\frac{42}{1}\times 30+0\times 70$$

Anything divided by one gives itself.

$$42\times 30+0\times 70$$

Multiply 42 and 30 to get 1260.

$$1260+0\times 70$$

Multiply 0 and 70 to get 0.

$$1260+0$$

Add 1260 and 0 to get 1260.

$$1260$$

Factor

$$2^{2}\times 3^{2}\times 5\times 7$$
