Question

A baby weighs $132$ $\mathrm{ounces}$ when it is born. The baby gained $60$ $\mathrm{ounces}$. How many pounds does the baby weigh now?

Answer 1

Step 1: Compute the baby's weight:

The baby's weight when the baby is born is $132\mathrm{ounces}$.

The baby gained $60$ $\mathrm{ounces}$.

Now, the weight of the baby is $132+60,\mathrm{i}.\mathrm{e}.192\mathrm{ounces}$

Step 2: Conversion of units:

The relation between $\mathrm{ounces}$ and $\mathrm{pound}$ is $1\mathrm{ounce}=0.0625\mathrm{pound}$.

Multiply $192$ by $0.0625$ to obtain the weight in the unit pound.

$192\times 0.0625=12$

Hence, now the weight of the baby is $12$ $\mathrm{pounds}$.
