The weight of an object on the moon is

Tanzania [10]

Answer:

40 2/5Ibs or $40\frac{2}{5}$ lbs

Step-by-step explanation:

Let weight of object on the moon be represented = Wm

weight of object on the Earth = We

In the above question, we are told:

The weight of an object on the moon is

5 of its weight on Earth.

Hence, mathematically, this is represented as:

5Wm = We

If a moon rock weighs 202 lbs on Earth

5Wm = 202lbs

Wm = 202lbs/5

Wm = $40\frac{2}{5}$ Ibs

Therefore, the moon rock weighs $40\frac{2}{5}$ Ibs on the moon.

Use the conversions given below to change 83 kg into stones.

eduard

83 kg converted to stones is 13 stones.

Step-by-step explanation:

Given,

We have to convert 83 kg to stones.

As it is given,

1 kg = 2.2 pounds

83 kg = 2.2*83 pounds

83 kg = 182.6 pounds

Now,

14 pounds = 1 stone

1 pound = $\frac{1}{14}\ stones$

182.6 pounds = $\frac{1}{14}*182.6$

182.6 pounds = 13.04 stones

Rounding to one dp

182.6 pounds = 13.0 stones

83 kg converted to stones is 13 stones.
