Question

Last year, Robert grew 3 1/3 inches and his brother grew 1 2/3 inches. How much more did Robert grow than his brother?

Answer 1

When it says "how much more", it means to find the difference between the siblings' growth by subtracting their growths.

Step 1: Convert both mixed numbers to improper fractions

$3\frac{1}{3}- 1\frac{2}{3}$ Learn how to do that here: brainly.com/question/13099965

$3\frac{1}{3}\\\\3\times3=9\\9+1=10\\\\\frac{10}{3}$

$1\frac{2}{3}\\\\3\times 1 = 3\\3 + 2 = 5\\\\\frac{5}{3}$

$\frac{10}{3} - \frac{5}{3}$

Step 2: Subtract

10 - 5 = 5

$\frac{5}{3}$ or $\bold {1\frac{2}{3}}$

Therefore, Robert grew $\bold {1\frac{2}{3}}$ more than his brother.

Answer 2

The answer to the question is Robert grew 1 2/3 inch taller that his brother
