Solution Steps

Expand \frac{7}{3.5} by multiplying both numerator and the denominator by 10.

$$\frac{70}{35}=\frac{14}{7}\text{ and }\frac{14}{7}=\frac{15.6}{7.8}$$

Divide 70 by 35 to get 2.

$$2=\frac{14}{7}\text{ and }\frac{14}{7}=\frac{15.6}{7.8}$$

Divide 14 by 7 to get 2.

$$2=2\text{ and }\frac{14}{7}=\frac{15.6}{7.8}$$

Compare 2 and 2.

$$\text{true}\text{ and }\frac{14}{7}=\frac{15.6}{7.8}$$

Divide 14 by 7 to get 2.

$$\text{true}\text{ and }2=\frac{15.6}{7.8}$$

Expand \frac{15.6}{7.8} by multiplying both numerator and the denominator by 10.

$$\text{true}\text{ and }2=\frac{156}{78}$$

Divide 156 by 78 to get 2.

$$\text{true}\text{ and }2=2$$

Compare 2 and 2.

$$\text{true}\text{ and }\text{true}$$

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

$$\text{true}$$
