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.

Can you work out the

total mass of this group

of gibbons? Remember

to take a careful look at

The mode

130 kg

First, you should

convert the

masses of the gibbons

into the same unit.

Then, you

simply add

up their masses.
