2.) 26% of 72

3.) 350 seats in an auditorium , 140% number of seats in the orgiinal auditorium, how many were in the orginal Aud?

Answer 1

1.) 60 is what % of 30
60 = 2*30 = 200% 30

2.) 26% of 72 = .26*72 = 18.72

3.) 350 seats in an auditorium , 140% number of seats in the orgiinal auditorium, how many were in the orginal Aud?
x = # of seats in original auditorium
350 = 1.4x
x = 350/1.4 = 250

Answer 2

Percentages are not difficult once you understand the formula in which to calculate them.

Using problem 1 as an example, you would set up the equation as follows:

60/30 = x/100
You want to find out what percent (x/100)

If you cross multiply the two fractions, you get:

6000/30 =x

Divide 6000 by 30 and you get:

200 = x

60 is 200% of 30

2. 26% of 72

You want to find how much out of 72 is 26%
26/100 = x/72

Again, cross multiply
1872 = 100x

Divide each side by 100 to get the x alone

18.72 = x

18.72 is 26% of 72

3. 350 seats in an auditorium, 140% number of seats in the original auditorium, how many were in the original auditorium?

140/100 = x/350

Cross multiply:
140x=35000

Divide by 140:
x=250

350 is 140% of 250

Answer 3

1) 60*100/30=200%

2) 72*26/100= 18.72

3) 350*100/140= 250

Answer 4

1.) 60 is 200% of 30
2.) 26% of 72 is 72 * .26 = 18.72
3.) 350 /1.4 = 250

Answer 5

60 is 200% of 30

26% of 72 is 18.72

250 seats in the original

Answer 6

1. 200%
2. 18.72
3. 250
