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>

If quadrilateral ABCD is congruent to quadrilateral EFGH, then what corresponding side is congruent to side FG? A) Side AB
BartSMP [9]

Two congruent quadrilaterals have congruent corresponding sides and angles. This means that if quadrilateral ABCD is congruent to quadrilateral EFGH, then:

  • AB≅EF;
  • BC≅FG;
  • CD≅GH;
  • AD≅EH;
  • ∠A≅∠E;
  • ∠B≅∠F;
  • ∠C≅∠G;
  • ∠D≅∠H.

Answer: correct choice is B (FG is congruent to side BC)
