Hi Nickayla, let's figure out how much weight David has gained since he was born by looking at these mixed numbers.
Weight Difference Calculation
We are given that his current weight is eighty-three and three quarters pounds, and his birth weight was six and one quarter pounds.
To find out how much more he weighs now, we need to subtract the birth weight from his current weight.
A simple way to handle mixed numbers is to deal with the whole numbers and the fractions separately. Let's start with the whole numbers: eighty-three minus six.
Eighty-three minus six is seventy-seven.
