Respuesta :

Answer:

1) 18

2) 30

3) 6

4) 3000

5) 5

Explanation:

1

25+15+20=60

x/60 = 60/100

x/60 = 3/5

x= 60(3/5)

x=36

50% of 36 is 18

2

x/48 = 75/100

x/48 = 3/4

x= 48(3/4)

x=30

3

x/30 = 60/100

x/30 = 3/5

x = 30(3/5)

x = 6

4

rate = boxes per day per person

r = 1500/4/6

r=62.5

62.5 = x/6/8

500 = x/6

3000 = x

5

rate = task per day per worker

r = 1/7/5

r=0.02857142857

0.02857142857 = 1/x/7

0.2 = 1/x

0.2x = 1

x = 0.2

1/0.2 = 5
