Explanation:

Question 22

Step1: Recall percentage to fraction

To convert a percentage to a fraction, we write the percentage as a fraction with a denominator of 100. So, 70% can be written as $\frac{70}{100}$.

Step2: Simplify the fraction

We find the greatest common divisor (GCD) of 70 and 100, which is 10. Then we divide both the numerator and the denominator by 10: $\frac{70\div10}{100\div10}=\frac{7}{10}$.

Step1: Recall percentage to decimal

To convert a percentage to a decimal, we divide the percentage value by 100. So, for 45%, we perform the operation $45\div100$.

Step2: Perform the division

Dividing 45 by 100 gives 0.45 (since dividing by 100 moves the decimal point two places to the left).

Answer:

$\frac{7}{10}$
