Answer 1

1) 2/7 * 3/5 = 6/35

2) 3/4 * 5/6 = 15/24 = 5/8

3) 4/7 * 7/9 = 4/9

4) 15/16 * 48/55 = 3/1 * 3/11 = 9/11

5) 22/25 * 10/77 = 2/5 * 2/7 = 4/35

6) 13/24 * 16/39 = 1/3 * 2/3 = 2/9

7) 6/35 * 14/15 = 2/5 * 2/5 = 4/25

8) 36/85 * 34/39 = 408/1105 = 24/65

Answer 2

I can help you with your math problems. Here are the answers and the steps:

1) $$\frac{2}{7} \times \frac{3}{5} = \frac{6}{35}$$ To find the product of two fractions, we multiply the numerators and the denominators.

2) $$\frac{3}{4} \times \frac{5}{6} = \frac{15}{24}$$ We use the same method as before, and then we simplify the fraction by dividing both the numerator and the denominator by 3.

3) $$\frac{4}{7} \times \frac{7}{9} = \frac{28}{63}$$ We multiply the fractions and then we simplify by dividing both the numerator and the denominator by 7.

4) $$\frac{15}{16} \times \frac{48}{55} = \frac{720}{880}$$ We multiply the fractions and then we simplify by dividing both the numerator and the denominator by 40.

5) $$\frac{22}{25} \times \frac{10}{77} = \frac{220}{1925}$$ We multiply the fractions and then we simplify by dividing both the numerator and the denominator by 5.

6) $$\frac{13}{24} \times \frac{16}{39} = \frac{208}{936}$$ We multiply the fractions and then we simplify by dividing both the numerator and the denominator by 8.

7) $$\frac{6}{35} \times \frac{14}{15} = \frac{84}{525}$$ We multiply the fractions and then we simplify by dividing both the numerator and the denominator by 21.

8) $$\frac{36}{85} \times \frac{34}{39} = \frac{1224}{3315}$$ We multiply the fractions and then we simplify by dividing both the numerator and the denominator by 17.
