Question

1. Express each of the following as a ratio in the simplest form: a) 0.05% ​

Answer 1

Step-by-step explanation:

0.05% = 5/100

5/100=1/20

Answer is 1/20

Answer 2

Answer: 5:1

Explanation:

• At first, we need to convert the percentage into fraction.

$0.05\% \\ = \frac{5}{100} \% \\ = \frac{5}{100} \times 100 \\ = \frac{500}{100} \\ = \frac{5}{1} \\ = 5$

• Now, we need to write the fraction in ratio form.
• Here, we see that The percentage has become a whole number after simplifying it. For this, we need to use the number 1 as denominator.
• For changing it into ratio, we need to write the numerator as antecedent and the denominator as consequent.

So,

$5 \\ = \frac{5}{1} \\ = 5:1$

∴ 0.05 in simplest form is 5:1
