The largest value among 4/5, 80%, 0.801 and (.9)^2 is (1) 4/5 (2) 80% (3) 0.801

Question

The largest value among \(\frac{4}{5}\), 80%, 0.801 and \((.9)^2\) is

(1) \(\frac{4}{5}\)

(2) 80%

(3) 0.801

(4) \((.9)^2\)

Answer 1

Correct option is: (4) \((.9)^2\)

(1) \(\frac{4}{5} = 0.8\)

(2) \(80 \% = \frac{80}{100} = \frac{8}{10} = 0.8\)

(3) 0.801 = 0.801

(4) \((.9)^2 = 0.9 \times 0.9 = 0.81\)

Thus, the largest value is \(0.81 / (.9)^2\)
