Answer 2

Answer:

17) 3.88

18) .66

19) 0.63 or 31

20) 0.06 or 3.23

Step-by-step explanation:

2x3+1 =7

1. 7/3 ÷ 3/5 = 7/3 x 5/3 = 35/9 = 3.88
2. 4/9÷ 2/3 = 4/9 x 3/2 = 12/18 = .66
3. 4x7+3 = 31.... 31/7 ÷ 7 = 31 or 31/7 x 1/7 = 31/49 = 0.63 or 31 ÷ 7 = 31/7 x 7/1 = 217/7 = 31
4. 6/13 ÷ 7 = 6/13 x 1/7 = 6/91 = 0.06 or 6/13x7/1 = 42/13 = 3.23

i've actually forgot that if denominator is not there and if we considered denominator 1 so it it's reciprocate or not in 19 and 20 question
