Question

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

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

$w=4.5\times 1kg$

now, we can replace 1kg

and we get

$w=4.5\times 2.2lb$

$w=9.9lb$

In ounces:

We have got

$w=9.9lb$

we know that

1 lb=16 oz

so, we can also write as

$w=9.9\times 1lb$

we can replace 1lb

and we get

$w=9.9\times 16 oz$

$w=158.4 oz$.............Answer
