A lap is 6/5 miles
minimum 15 / 2 miles
(15/2)/(6/5) = 25/4 = 6 and 1/4 laps minimum which has to be rounded up to 7 laps

1 1/5 can be written as 6/5
7 1/2 can be written as 15/2
Let X be the number of laps Kellyn wants to jog to meet her 7 1/2 mile goal:
6/5x = 15/2                Multiply both sides by (5/6), the inverse of 6/5
x = 15(5) / 2 ( 6) 
x = 75 / 12
X = 25 / 4, or 6 and 1/4 laps

crystal is picking blueberries.so far,she has filled 2/3 of her basket,and the blueberries weigh 3/4pound .the equation 2/3w=3/4
vesna_86 [32]
In order to do this, we multiply both sides be the amount that would make the left side equal to 1.  This number is the reciprocal of the fraction, so we multiply both sides by 3/2.  This is equal to:

w = 9/8

So, the blueberries in crystal's basket will weigh 9/8 pounds when it is full.
