MEASUREMENT • CALCULATING WITH MASS 185
To change 85 g to
kilograms, we just
divide by 1000:
85 ÷ 1000 = 0.085 kg
Now it’s much clearer which
order the animals go in, and
we can order the numbers from
largest to smallest.
The tiger has the largest mass of
130 kg, the snake has the next
largest at 35 kg, and the parrot is the
smallest at just 0.085 kg.
