Answer 1

it would help if you used real notation. I shall guess, and if I get it wrong, I'm sure you can fix it and correct the results.

#18: 2 and 1 over 7, times, 3 over 4
2 1/7 * 3/4 = 15/7 * 3/4 = 45/28

#19: 6 over 7, divide, 1 over 4
6/7 ÷ 1/4 = 6/7 * 4/1 = 24/7

#20: negitave 5 over 3, divide, negitive, 15 over 7
-5/3 ÷ -15/7 = -5/3 * -7/15 = 35/45 = 7/9

Answer 2

thank you, i will remember to use real notations next time!
