Verify

Solution Steps

Calculate 10 to the power of -1 and get \frac{1}{10}.

$$\frac{7}{22}=7\left(2\times \frac{1}{10}+2\right)$$

Multiply 2 and \frac{1}{10} to get \frac{1}{5}.

$$\frac{7}{22}=7\left(\frac{1}{5}+2\right)$$

Add \frac{1}{5} and 2 to get \frac{11}{5}.

$$\frac{7}{22}=7\times \frac{11}{5}$$

Multiply 7 and \frac{11}{5} to get \frac{77}{5}.

$$\frac{7}{22}=\frac{77}{5}$$

Least common multiple of 22 and 5 is 110. Convert \frac{7}{22} and \frac{77}{5} to fractions with denominator 110.

$$\frac{35}{110}=\frac{1694}{110}$$

Compare \frac{35}{110} and \frac{1694}{110}.

$$\text{false}$$
