A percent is 1 part out of 100.<\/p>\n\n\n\n

1% is equal to 1\/100 or 0.01<\/p>\n\n\n\n

Proportions can be used to solve percent problems.<\/p>\n\n\n\n

part \/ whole = percent \/ 100<\/p>\n\n\n\n

\ud83d\udd14 What is 10% of 90?<\/p>\n<\/div><\/div>\n\n\n\n

The whole is 90.<\/p>\n\n\n\n

The percent is 10%.<\/p>\n\n\n\n

Let n<\/em> represent the part.<\/p>\n\n\n\n

Write a proportion to solve for n<\/em>.<\/p>\n\n\n\n

n \/ 90 = 10 \/ 100<\/p>\n\n\n\n

100n = 10 \u00b7 90<\/p>\n\n\n\n

100n = 900<\/p>\n\n\n\n

100n \u00f7 100 = 900 \u00f7 100<\/p>\n\n\n\n

n = 9<\/p>\n\n\n\n

10% of 90 is 9.<\/p>\n\n\n\n

You could also find the answer by writing and solving an equation:<\/p>\n\n\n\n

part = percentage of whole<\/p>\n\n\n\n

n = 10% \u00b7 90<\/p>\n\n\n\n

n = 0.1 \u00b7 90<\/p>\n\n\n\n

n = 9<\/p>\n\n\n\n

10% of 90 is 9.<\/p>\n<\/div><\/div>\n\n\n\n

100% of 59 = _____<\/p>\n<\/div><\/div>\n\n\n\n

100% of a number is the entire number<\/em>. 100% of 59 is 59. You can check this by doing the maths.<\/p>\n\n\n\n

The whole is 59.<\/p>\n\n\n\n

The percent is 100%.<\/p>\n\n\n\n

Let n<\/em> represent the part.<\/p>\n\n\n\n

Write a proportion to solve for n<\/em>.<\/p>\n\n\n\n

n\/59 = 100\/100<\/p>\n\n\n\n

100n = 100 \u00b7 59<\/p>\n\n\n\n

100n = 5,900<\/p>\n\n\n\n

100n \u00f7 100 = 5,900 \u00f7 100<\/p>\n\n\n\n

n = 59<\/p>\n\n\n\n

100% of 59 = 59<\/p>\n\n\n\n

You could also find the answer by writing and solving an equation:<\/p>\n\n\n\n

part = percentage of whole<\/p>\n\n\n\n

n = 100% \u00b7 59<\/p>\n\n\n\n

n = 1 \u00b7 59<\/p>\n\n\n\n

n = 59<\/p>\n\n\n\n

80% of 40 =____<\/p>\n<\/div><\/div>\n\n\n\n

The whole is 40.<\/p>\n\n\n\n

The percent is 80%.<\/p>\n\n\n\n

Let n represent the part.<\/p>\n\n\n\n

Write a proportion to solve for n.<\/p>\n\n\n\n

n\/40 = 80\/100<\/p>\n\n\n\n

100n = 80 \u00b7 40<\/p>\n\n\n\n

100n = 3,200<\/p>\n\n\n\n

100n \u00f7 100 = 3,200 \u00f7 100<\/p>\n\n\n\n

n = 32<\/p>\n\n\n\n

80% of 40 = 32<\/p>\n\n\n\n

You could also find the answer by writing and solving an equation:<\/p>\n\n\n\n

part = percentage of whole<\/p>\n\n\n\n

n = 80% \u00b7 40<\/p>\n\n\n\n

n = 0.8 \u00b7 40<\/p>\n\n\n\n

n = 32<\/p>\n\n\n\n

80% of 40 = 32<\/p>\n<\/div><\/div>\n\n\n\n
