How would you represent 49% as a fraction?

• 49/50

• 49/100

• 24/50

• 48/100

Answer explanation

To represent 49% as a fraction, you write it as 49/100 since the denominator of a percentage is always 100.

• 50%
• 80%
• 60%
• 25%

A percent means per 100, so it is expressed as a fraction with a _________ of 100.

Answer explanation

If you scored 18 out of 20 on a test, what percentage did you score?

• 80%

• 85%

• 90%

• 95%

Answer explanation

Set the number of questions correct over the total number of questions. Set this fraction to another with the denominator of 100 to represent the percent of 100 (whole). Apply the scale factor (5) to the numerator and denominator to generate the equivalent percentage for the score of the test.

How do you find equivalent fractions by multiplication?

• Multiply the numerator by a number and the denominator by another number

• Divid the numerator and denominator by the same number

• Multiply both the numerator and denominator by the same number

• Multiply the numerator by two and leave the denominator the same

Answer explanation

Even when we reduce a fraction to find it's equivalent, we multiply it by a fraction less than one to decrease the value of the numerator and denominator.

To scale 10 to 100 we must multiply by 10 in the denominator. To generate an equivalent fraction we must multiply the numerator by the same amount. 7 time 10 is 70.
