Question

3 1/3 * 3 3/5 = ... ; 2 2/5 * 13 1/3 =

Answer 1

1)это делает 10/3 *18/5

дальше сокращаются 10 и 5 и 3 и 18

получается:

12

Answer 2

To solve these multiplication problems involving mixed numbers, follow these steps:

1. Convert the mixed numbers to improper fractions.
2. Multiply the improper fractions.
3. Convert the result back to a mixed number if needed.

Let's solve the problems:

1. $3 \frac{1}{3} \times 3 \frac{3}{5}$:

Step 1: Convert mixed numbers to improper fractions: $3 \frac{1}{3} = \frac{10}{3}$ $3 \frac{3}{5} = \frac{18}{5}$

Step 2: Multiply the improper fractions: $\frac{10}{3} \times \frac{18}{5} = \frac{10 \times 18}{3 \times 5} = \frac{180}{15}$

Step 3: Simplify the fraction, if possible: $\frac{180}{15} = \frac{12}{1} = 12$

So, $3 \frac{1}{3} \times 3 \frac{3}{5} = 12$.

2. $2 \frac{2}{5} \times 13 \frac{1}{3}$:

Step 1: Convert mixed numbers to improper fractions: $2 \frac{2}{5} = \frac{12}{5}$ $13 \frac{1}{3} = \frac{40}{3}$

Step 2: Multiply the improper fractions: $\frac{12}{5} \times \frac{40}{3} = \frac{12 \times 40}{5 \times 3} = \frac{480}{15}$

Step 3: Simplify the fraction, if possible: $\frac{480}{15} = \frac{32}{1} = 32$

So, $2 \frac{2}{5} \times 13 \frac{1}{3} = 32$.
