Weight and Mass

Example: Fill in the blanks

a)      3 tonnes= _____ pounds

b)      12 pounds= _____ ounces

c)       50,000 ounces= _____ tonnes

Solution:

a)      Using the chart above, we see that 1 tonne is equal to 2000 pounds. Therefore, we multiply 3 tonnes by 2000.

3 x 2000= 6000
3 tonnes is equal to 6000 pounds.

Using a similar method for questions b) and c), we can fill in the other blanks

a)      3 tonnes= 6000 pounds

b)      12 pounds= 12 x 12= 144 ounces

c)       50,000 ounces= 50,000 x 0.000042= 2.1 tonnes
