Final answer:
Katori grew 3 2/3 inches more than Michael. We calculated the difference by subtracting Michael's growth from Katori's, with the result expressed as a mixed number.
Step-by-step explanation:
To find out how much more Katori grew than Michael, we need to subtract the amount Michael grew from the amount Katori grew. Katori grew 4 inches, and Michael grew 1/3 of an inch. The difference in their growth can be calculated as follows:
- Katori's growth: 4 inches
- Michael's growth: 1/3 inch
- Difference in growth (Katori - Michael): 4 - 1/3 inches
To subtract a fraction from a whole number, we can think of the whole number as being over 1 to give it a common denominator with the fraction:
- 4 inches can be written as 4/1 inches,
- So, 4/1 - 1/3 = (4 × 3)/3 - (1 × 1)/3 = (12 - 1)/3 = 11/3 inches.
Therefore, Katori grew 11/3 inches or 3 2/3 inches more than Michael.
