Question

Does anyone know how to do this

Answer 1

1. 100% - all the other percentages and that equals 25%

2. swimming = 30%
football = 25% = 100 ppl
5% = 20 ppl
( i divided both 25 and 100 by 5 )

30% = 120 ppl
(i multiplied both 5 and 20 by 6)

120


3. football = 25% = 25/100
baseball = 20% = 20/100

25/100+20/100= 45/100 and that simplifies to 9/20

9/20


4. (from question 2)
5% = 20ppl
tennis = 10% = 40 ppl
(i multiplied the 5 and 20 by 2)

football= 100

100+40=140

140


5.
football= 100
tennis= 40
volleyball= 60
swimming= 120
baseball= 80

add them all up

400

Answer 2

1. 25%

2. unsure

`(25)/(100) +(20)/(100) = (45)/(100) or (9)/(20)` (this is #3)

4.
`(25)/(100) + (10)/(100) = (35)/(100) or (7)/(20)` (not sure if you're supposed to use a fraction, so this might be wrong)
