1. Gordon has 25 gum balls in a bag. He has 7 red, 5 green, 2 yellow, 4 orange, 1 black, and 6 purple gum balls.
He reaches into the bag without looking and pulls out one gum ball.
Write a fraction, a decimal, and a percent to describe the probability
of Gordon picking each colour of gum ball.
a) purple:
b) black:
c) pink:
d) red or yellow:

a) 6/25, .24, 24%

b)1/25, .04, 4%

c) 0/25, .00, 0% (there is no pink)

d) 9/25, .36, 36%

Step-by-step explanation:

To find the fraction just put the number of gumballs in that color in front of the total (25)

To find the decimal divide the number of gumabalss that color by the total

The percentage is equal to the decimal in hundreths

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
