1 7/10244 3/88/9A. 15B. 7 1/2 kmC. 1 1/4 m
Step-by-step explanation:
1.
2 5/6 ÷ 3 3/4 = N
17/6 × 9/15 = 153/90
153/90 = 1 63/90
1 63/90 = 1 7/10
2.
8 ÷ 1/3 = N
8/1 × 3/1 = 24/1
24/1 = 24
3.
3 3/4 ÷ 6/7 = N
15/4 × 7/6 = 105/24
105/24 = 4 9/24
4 9/24 = 4 3/8
4.
4/9 ÷ 3/6 = N
4/9 × 6/3 = 24/27
24/27 = 8/9
A.
3/4 of 20 = N
3/4 × 20/1 = 60/4
60/4 = 15
B.
I'm not sure of my answer
2 1/4 × 3 1/3 = N
9/4 × 10/3 = 90/12
90/12 = 7 6/12
7 6/12 = 7 1/2
C.
12 1/2 ÷ 10 = N
25/2 × 1/10 = 25/20
25/20 = 1 1/4
