Solution Steps

Express \frac{\frac{12\times 1+18}{1}}{20} as a single fraction.

$$\frac{12\times 1+18}{20}=\frac{1}{20}\times \frac{1}{18}\text{ and }\frac{1}{20}\times \frac{1}{18}=\frac{1\times 10+19}{10}$$

Multiply 12 and 1 to get 12.

$$\frac{12+18}{20}=\frac{1}{20}\times \frac{1}{18}\text{ and }\frac{1}{20}\times \frac{1}{18}=\frac{1\times 10+19}{10}$$

Add 12 and 18 to get 30.

$$\frac{30}{20}=\frac{1}{20}\times \frac{1}{18}\text{ and }\frac{1}{20}\times \frac{1}{18}=\frac{1\times 10+19}{10}$$

Reduce the fraction \frac{30}{20} to lowest terms by extracting and canceling out 10.

$$\frac{3}{2}=\frac{1}{20}\times \frac{1}{18}\text{ and }\frac{1}{20}\times \frac{1}{18}=\frac{1\times 10+19}{10}$$

Multiply \frac{1}{20} times \frac{1}{18} by multiplying numerator times numerator and denominator times denominator.

$$\frac{3}{2}=\frac{1\times 1}{20\times 18}\text{ and }\frac{1}{20}\times \frac{1}{18}=\frac{1\times 10+19}{10}$$

Do the multiplications in the fraction \frac{1\times 1}{20\times 18}.

$$\frac{3}{2}=\frac{1}{360}\text{ and }\frac{1}{20}\times \frac{1}{18}=\frac{1\times 10+19}{10}$$

Least common multiple of 2 and 360 is 360. Convert \frac{3}{2} and \frac{1}{360} to fractions with denominator 360.

$$\frac{540}{360}=\frac{1}{360}\text{ and }\frac{1}{20}\times \frac{1}{18}=\frac{1\times 10+19}{10}$$

Compare \frac{540}{360} and \frac{1}{360}.

$$\text{false}\text{ and }\frac{1}{20}\times \frac{1}{18}=\frac{1\times 10+19}{10}$$

Multiply \frac{1}{20} times \frac{1}{18} by multiplying numerator times numerator and denominator times denominator.

$$\text{false}\text{ and }\frac{1\times 1}{20\times 18}=\frac{1\times 10+19}{10}$$

Do the multiplications in the fraction \frac{1\times 1}{20\times 18}.

$$\text{false}\text{ and }\frac{1}{360}=\frac{1\times 10+19}{10}$$

Multiply 1 and 10 to get 10.

$$\text{false}\text{ and }\frac{1}{360}=\frac{10+19}{10}$$

Add 10 and 19 to get 29.

$$\text{false}\text{ and }\frac{1}{360}=\frac{29}{10}$$

Least common multiple of 360 and 10 is 360. Convert \frac{1}{360} and \frac{29}{10} to fractions with denominator 360.

$$\text{false}\text{ and }\frac{1}{360}=\frac{1044}{360}$$

Compare \frac{1}{360} and \frac{1044}{360}.

$$\text{false}\text{ and }\text{false}$$

The conjunction of \text{false} and \text{false} is \text{false}.

$$\text{false}$$
