Question

A watermelon at the grocery store weighs 4.5 kg. How much does the watermelon weigh in pounds and ounces?

If needed, round the ounces to the nearest tenth.

Conversion ratios:

1 lb = 16 oz
1 kg = 2.2 lb

Answer 1

We are given

weight of watermelon =4.5kg

In pounds:

we know that

1kg=2.2lb

so, we have

`w=4.5kg`

we can also write as

`w=4.5* 1kg`

now, we can replace 1kg

and we get

`w=4.5* 2.2lb`

`w=9.9lb`

In ounces:

We have got

`w=9.9lb`

we know that

1 lb=16 oz

so, we can also write as

`w=9.9* 1lb`

we can replace 1lb

and we get

`w=9.9* 16 oz`

`w=158.4 oz`.............Answer
