Question

does anyone know how to do this

Answer 1

1. 25%

2. unsure

$\frac{25}{100} +\frac{20}{100} = \frac{45}{100} or \frac{9}{20}$ (this is #3)

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

5. unsure

Answer 2

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
