Answer 2

To calculate the given expressions, simply multiply the fractions:

a) (4/5) * (5/7) = (4 * 5) / (5 * 7) = 20 / 35 = 4 / 7

b) (8/9) * (3/5) = (8 * 3) / (9 * 5) = 24 / 45 = 8 / 15

c) (9/2) * (2/9) = (9 * 2) / (2 * 9) = 18 / 18 = 1

d) (8/21) * (7/10) = (8 * 7) / (21 * 10) = 56 / 210 = 4 / 15

e) (8/15) * (25/28) = (8 * 25) / (15 * 28) = 200 / 420 = 10 / 21
