Question

What is the result when the number 79 is decreased by 17%?

Answer 1

65.57

Explanation:

Method 1:

`(y)/(79) :(17)/(100)`

y · 100 = 17 · 79

100y = 1343

100y ÷ 100 = 1343 ÷ 100

y = 13.43

79 - 13.43

65.57

Method 2:

100% - 17% = 83%

`(y)/(79) :(83)/(100)`

y · 100 = 83 · 79

100y = 6557

100y ÷ 100 = 6557 ÷ 100

y = 65.57

Answer 2

65.57 should be the correct answer!

Explanation:

Here is the whole work I did, hope this helps!

100 - 17 = 83

79 x 0.83 = 65.57
