Question

Forty of Dan's 50 answers were correct, what percent of Dan's answers were correct?
​

Answer 1

80%

Explanation:

As a fraction this would be:

40/50

We could do some mental mathematics and work out what 40÷50 is and then ×100 to get a percentage.

Or we can just double the fraction to make the denominator 100:

40/50×2/2

80/100

Now we multiply this by 100 (basically remove the denominator):

80%

Answer 2

Answer: 80%

Explanation:

40/50 = 80/100 = .8 then move decimal over 2 places to the right for percent. .8 to 8.0 to 80.0
