48 is 80% of 60

48 of 60 can be written as 48/60

Multiply both the numerator and the denominator by 100
48/60 · 100/100 = 80/100 = .8 = 80%

If you are using a calculator, simply enter 48 ÷ 60 · 100 which will give you 80 as the answer.

Answer:

The correct answer is 1.

In order to solve the problem \frac{3}{9}  + \frac{2}{3}, we need can use two methods.

Method 1: Make the denominators the same.

3/9 + 2/3 =

3/9 + 6/9 =

9/9 =

1

Method 2: Turn both fraction into decimals (<em>by dividing the numerator by the denominator</em>.)

3/9 or 3 ÷ 9 = 0.3 (when rounded to the nearest tenth)

2/3 or 2 ÷ 3 = 0.7 (when rounded to the nearest tenth)

0.3 + 0.7 = 1

Therefore, the answer to this question is 1.
