5(x-3)+7=5x-8
5*x=5x        5*3=15        
5x-15+7=5x-8
15+7=22    
5x-22=5x-8
5x+5x=10x
10x-22=8
22+8=30
10x=30
---------- (Divide by 10 to get x alone)
    10
x=3

When a jar of fruit is 2/3 of the way full it can hold 2 1/4 cups of fruit what fraction of the jar is full when it only contain
Natali [406]

Answer:

8/27

Step-by-step explanation:

<h2><u>Fractions</u></h2>

a jar of fruit is 2/3 of the way full it can hold 2 1/4 cups of fruit

what fraction of the jar is full when it only contains one cup of fruit?

by using these statements , we can solve this through <u>cross multiplication</u>:

fraction that the jar is full                   :           number of cups of fruit

                 \frac{2}{3}                                         :                        2 \frac{1}{4}

                 x                                         :                        1

\frac{2}{3}  = 2 \frac{1}{4} x

convert 2 \frac{1}{4} from a mixed fraction to an improper fraction

hence 2 1/4  = 9/4

solve

\frac{2}{3}  = \frac{9}{4} x.

x = \frac{2}{3} /  \frac{9}{4}

<u>x = 8/27</u>

<h3><u>when the cup contains one cup of fruit its fraction 8/27 full </u></h3>
