How do i convert measurements?

Question

with problems like these

a. 2.5 h=______min

b.80 oz = ________lb

c.20c= _____qt

d. 900 sec=_______min

Answer 1

60 minutes in 1 hour

16 oz in 1 lb

2 cups in 1 quart

60 seconds in 1 minute

multiply or divide as needed

Answer 2

In each case, multiply the original number by the conversion factor.

For example:

2.5 hours x 60 min/1 hour = 150 minutes

900 secs x 1 min/60 sec = 15 minutes

Make sure the numerator is the unit you want and the denominator is the unit you started with, which cancels out.

Answer 3

a. 2.5 h=______min

2.5 hr x 60min/hr = 2.5 x 60 min = 150 min

b.80 oz = ________lb

80 oz x 1lb/16oz = 80/16 lb = 5 lb

c.20c= _____qt

20 cups x 1qt/4cups = 20/4 qt = 5 qt

d. 900 sec=_______min

900 sec x 1min/60sec = 900/60 min = 15 min

Conversion factors:

1 hr = 60 min

1 min = 60 sec

1 qt = 2 pint & 1 pint = 2 cups

1 qt = 4 cups

1 lb = 16 oz
