Of all the students that Mikey surveyed, 30% said they play baseball. If 21 students play baseball, how many students did Mikey survey

70 students

Step-by-step explanation:

As, 30% Mike surveyed

And these 30% are 21 students

So 30% of X = 21

= 30/100 x X = 21

= 30X = 2100

So X = 2100/30

X = 70

So 70 students were surveyed

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

step-by-step explanation:

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
