Answer 1

Ответ:

2 1/3 * 1 1/5 = 7*6/3*5 = 14/5 = 2 4/5

2 7/9 * 3 3/5 = 25*18/9*5 = 10

2 1/2 * 1 3/5 = 5*8/2*5 = 4

3 7/9 * 1 1/17 = 34*18/9*17 = 4

7 1/2 * 2 4/15 = 15*34/2*15 = 17

5 1/6 * 3 1/7 = 31*22/6*7 = 341/21 = 16 5/21

3 3/7 * 2 1/3 = 24*7/7*3 = 8

7 1/3 * 2 2/11 = 22*24/3*11 = 16

Answer 2

Sure, let's solve these multiplication problems step by step:

1. $2 \frac{1}{3} \times 1 \frac{1}{5}$ To multiply mixed numbers, first convert them into improper fractions: $2 \frac{1}{3} = \frac{7}{3}$ $1 \frac{1}{5} = \frac{6}{5}$

Now, multiply the fractions: $\frac{7}{3} \times \frac{6}{5} = \frac{42}{15}$

Reduce the fraction to its simplest form: $\frac{42}{15} = \frac{14}{5}$

So, $2 \frac{1}{3} \times 1 \frac{1}{5} = 2 \frac{2}{5} = \frac{12}{5}$.

2. $2 \frac{7}{9} \times 3 \frac{3}{5}$ Convert the mixed numbers into improper fractions: $2 \frac{7}{9} = \frac{25}{9}$ $3 \frac{3}{5} = \frac{18}{5}$

Now, multiply the fractions: $\frac{25}{9} \times \frac{18}{5} = \frac{450}{45}$

Reduce the fraction to its simplest form: $\frac{450}{45} = \frac{10}{1} = 10$

So, $2 \frac{7}{9} \times 3 \frac{3}{5} = 10$.

I'll provide answers for the remaining problems as well:

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

4. $3 \frac{7}{9} \times 1 \frac{1}{17} = 3 \frac{8}{153}$

5. $7 \frac{1}{2} \times 2 \frac{4}{15} = 18 \frac{1}{5}$

6. $5 \frac{1}{6} \times 3 \frac{1}{7} = 16 \frac{5}{42}$

7. $3 \frac{3}{7} \times 2 \frac{1}{3} = 8 \frac{18}{21} = 9 \frac{3}{7}$

8. $7 \frac{1}{3} \times 2 \frac{2}{11} = 16 \frac{1}{33}$

I hope this helps! If you have any more questions or need further assistance, feel free to ask.
