To solve for f, you need to isolate/get the variable by itself in the equation:

4(0.5f - 0.25) = 6 + f       Distribute 4 into (0.5f - 0.25)

(4)0.5f + (4)(-0.25) = 6 + f

2f - 1 = 6 + f        Subtract f on both sides to get "f" on one side of the equation

2f - f - 1 = 6 + f - f

f - 1 = 6       Add 1 on both sides to get "f" by itself

f - 1 + 1 = 6 + 1

f = 7

PROOF

4(0.5f - 0.25) = 6 + f      Substitute/plug in 7 into "f" since f = 7

4(0.5(7) - 0.25) = 6 + 7

4(3.5 - 0.25) = 13

4(3.25) = 13

13 = 13

Charlotte spent 1/2 of the day shopping at all. She spent 1/4 of this time trying on jeans. What fraction of the day did Charlot
RideAnS [48]

Answer:

Charlotte spend \frac{1}{8} of day trying on jeans

Step-by-step explanation:

Charlotte spent part of day on shopping = \frac{1}{2}

She spent part of shopping time on trying jeans =\frac{1}{4}

We are supposed to find What fraction of the day did Charlotte spend trying on jeans.

She spent fraction of the day in trying jeans = \frac{1}{2} \times \frac{1}{4}

She spent fraction of the day in trying jeans = \frac{1}{8}

Hence Charlotte spend \frac{1}{8} of day trying on jeans
