2) 7/40
3) 7
4) 1 5/12
5) 98,000
Step-by-step explanation(1):
18 ÷ 9 = 2
27 ÷ 9 = 3
Step-by-step explanation(2):
7 · 1 = 7
8 · 5 = 40
Step-by-step explanation(3):
2 · 21 = 42
3 · 1 = 3
42 ÷ 3 = 14
21 - 14 = 7
Step-by-step explanation(4):
2 · 4 = 8
3 · 4 = 12
3 · 3 = 9
3 · 4 = 12
= 8/12 + 9/12
= 17/12
= 1 5/12
Step-by-step explanation(5):
