There were 25 runners competing in a race. The number of runners who finished ahead of Paula was one-third the number of runners

alexandr402 [8]

Answer:

7th Place

Step-by-step explanation:

Seeing as how the number of runners in front of Paula is $\frac{1}{3}$ the number of runners behind her,

Assign the number of people behind Paula to a variable:

# of people behind Paula = b, which means

# of people ahead of Paula = $\frac{1}{3}$ b

Use the variable to make an equation:

b (people behind Paula) + $\frac{1}{3}$ b (people ahead of Paula) + 1 (Paula) = 25

b + $\frac{1}{3}$ b + 1 = 25

Solve for b:

b + $\frac{1}{3}$ b + 1 = 25

b + $\frac{1}{3}$ b = 24

$\frac{4}{3}$ b = 24

b = 18

If there are 18 people behind Paula, there are $\frac{1}{3}$ * 18 people in front of her, which is 6; This puts Paula in 7th place.

Ashley ran 3/4 of a mile each day on Monday, Wednesday and Friday. How many miles did she run in all?

dolphi86 [110]

Because she ran on 3 days total, you can multiply the 3/4 by 3.

3/4(3) = 2.25 miles
