Question

a baby boy weights 7 lb 8 oz. A five year old weights 48 lb. write the ratio of the baby's weight to the boys weight as a fraction in the simplest form

Answer 1

Weight of baby boy , w = 7 lb 8 oz .

Weight of 5 year kid , W = 48 lb .

We know , 16 oz = 1 lb .

So , w = 7 + 0.5 = 7.5 lb .

Now , ratio is :

$R=\dfrac{7.5}{48}\\\\R=\dfrac{5}{32}$

Therefore , the ratio of the baby's weight to the boys weight as a fraction is

$\dfrac{5}{32}$ .

Hence , this is the required solution .
