Diego is 59.5 inches tall. His brother is 40.125 inches tall. How much taller than his brother is Diego? Show your reasoning.
The correct answer and explanation is:
To find how much taller Diego is than his brother, we subtract the height of his brother from Diego’s height. Here’s the calculation:
Diego’s height = 59.5 inches
Brother’s height = 40.125 inches
The difference in height is:
59.5 inches – 40.125 inches = 19.375 inches
Therefore, Diego is 19.375 inches taller than his brother.
Explanation:
The first step is recognizing that both heights are given in inches, so there is no need to convert units. Now, to subtract 40.125 from 59.5, we align the decimal points and proceed with the subtraction as we would with whole numbers.
- Start by subtracting the numbers to the right of the decimal:
- Subtracting 0 from 5 gives 5.
- Subtracting 1 from 5 gives 4.
- Subtracting 2 from 9 gives 7.
- Moving to the whole number part:
- Subtracting 4 from 9 gives 5.
- Finally, subtracting 0 from 5 gives 5.
So the result is 19.375 inches. This means that Diego’s height exceeds his brother’s by 19.375 inches, which is a little over 19 inches.
