3)84/169

Answer 2

Ответ:

3/17÷2/15=3/17×15/2=45/34=1 11/34

2/11×4/17=8/187

12/13×7/13=84/169

Answer 3

Sure, let's solve each of these mathematical expressions step by step:

1. $\frac{3}{17} ÷ \frac{2}{15}$

To divide fractions, you can multiply by the reciprocal of the second fraction:

$\frac{3}{17} ÷ \frac{2}{15} = \frac{3}{17} \times \frac{15}{2} = \frac{3 \times 15}{17 \times 2}$

$= \frac{45}{34}$

2. $\frac{2}{11} \times \frac{4}{17}$

To multiply fractions, simply multiply the numerators and then multiply the denominators:

$\frac{2}{11} \times \frac{4}{17} = \frac{2 \times 4}{11 \times 17}$

$= \frac{8}{187}$

3. $\frac{12}{13} \times \frac{7}{13}$

Again, multiply the numerators and then multiply the denominators:

$\frac{12}{13} \times \frac{7}{13} = \frac{12 \times 7}{13 \times 13}$

$= \frac{84}{169}$
