What fraction of an hour is 12 minutes?

Question

What fraction of an hour is 12 minutes? Give your answer is its simplest form.

 

How many milimeters are there in 3/4 metre?

 

Write these fractions in order of size starting with the smallest:

3/4, 1/2, 5/8, 11/16

 

Answer 1

12/60 = 1/5. 12 minutes is 1/5 of an hour, or 20% of an hour

3/4 of a meter is .75 meters

one meter = 100 cm or 1000 mm

.75 x 1000 = 750 mm in 3/4 of a meter

1/2, 5/8, 11/16, 3/4

if the numerator is more than 1/2 the denominator the fraction is greater than 1/2

1/2 = 8/16 = 4/8 = 2/4, 1/2 is smallest

3/4= 6/8 = 12/16, 3/4 is largest

5/8 = 10/16. 10/16 is less than 11/16
