Julia swam 3/4 of a mile in the pool. if each lap is 1/16 of a mile, how many laps did she swim.

The answer is twelve because to Make the two fractions denominators equal you have to multiply the  numerator and denominator by 4 to get the denominators equal which gets you a fraction of 12/16 and if you divide that by 1/16 because that is how long each lap is then you get 16 which is the amount of laps they swam

The answer is twelve.

3/4 x 4 = 12/16

12/16 divided by 1/16 is 12z

1. d.90

2. e. none of these (80)

3. a. 0

4. b. 6

5. e. none of these (10)

6. a. 5

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
