Question

Find the greatest of these decimals:

• A. $$(0.2)^2$$
• B. $$(0.2)^{-1}$$
• C. $$0.\bar{2}$$
• D. 0.2

Answer 1

Answer:

$$(0.2)^{-1}$$

(A) (0.2)² = 0.04

(B) (0.2)^-1 = $\frac{1}{0.2}$

$=\frac{10}{2}=5$

(C) $0.\bar{2}=\frac{2}{9}$

(D) 0.2

now we can see

0.2^-1 is the greatest of them.
