52 is What Percent of 66?

Step by step

1. Divide the part by the whole: 52 ÷ 66 = 0.787879
2. Multiply by 100: 0.787879 × 100 = 78.7879%

How the answer is worked out

A percentage is a number out of 100. To find what percent 52 is of 66, imagine 66 split into 100 equal parts of 0.66 each. 52 contains 78.7879 of those parts, so 52 is 78.7879% of 66.

52 is more than three quarters of 66. The part that is left, 14, is the other 21.2121%.

Why calculate this?

Expressing one number as a percentage of another puts different-sized quantities on the same scale: test scores, shares of a budget, progress towards a goal.

• Test scores: 52 correct answers out of 66 is a score of 78.7879%, which on a common US grading scale is a C.
• Surveys: if 52 of 66 people answer “yes”, then 78.7879% said yes and 21.2121% did not.
• Savings goals: with $52 saved towards $66, you are 78.7879% of the way there and need $14 more.

A quicker way

Find 1% of 66 first: 66 ÷ 100 = 0.66. Then count how many of those fit into 52: 52 ÷ 0.66 = 78.7879.

Simplify the fraction first to make the division easier: 52/66 = 26/33, and 26/33 × 100 = 78.7879%.

Check the answer

Work backwards: 78.7879% of 66 is 0.787879 × 66 = 52. Getting 52 back shows the answer is right.

Rounding

Rounded to a whole number the percentage is 79, to one decimal place 78.8 and to two decimal places 78.79. Round only at the end: rounding halfway through a calculation can change the last digit.

The formula explained

percentage = part ÷ whole × 100. The part is the number you are asking about and the whole is the number after “of”. Dividing gives the fraction of the whole, and multiplying by 100 turns that fraction into a number out of 100.

Another worked example: 11 is what % of 6

1. Divide the part by the whole: 11 ÷ 6 = 1.833333
2. Multiply by 100: 1.833333 × 100 = 183.3333%

Dividing the wrong way round (whole ÷ part) gives a different answer. The number after “of” is always the whole, so it goes on the bottom.
