6. In a group of 50 children, 11 cannot swim. What percentage can swim?
Answer:
1. 561
2. 57%
3. 175
4. $ 27
5. 1000 g
6. 78%
Step-by-step explanation:
1. 3300 x .17 = 561
2. 7980/14000 = .57
.57 x 10% = 57%
3. 70 ÷ 40% = 175
175 x .40 = 70
4. 30 x .10 = 3
30 – 3 = $ 27
5. 26% of x = 260 gm
26
100 x 100 = 260
x = 260 x 100
26
x = 26000
26
x = 1000 g
6. 50 – 11 = 39
39/50 = .78
.78 x 100% = 78%
50 x .78 = 39
Hope it helps!
