siniylev [52]

Answer:

the two lengths= 194 each side

teh two widths= 49 on each side

Ashley uses 1/4 package of raisin for a fruit cake. She then uses 1/9 of the remainder for muffins. What fraction of the package
Flura [38]
\text {Fruit cake = } \dfrac{1}{4}

\text {Raisin left = } 1 -  \dfrac{1}{4} = \dfrac{4}{4} - \dfrac{1}{4} = \dfrac{3}{4}

\text {Muffins  = } \dfrac{1}{9}  \times  \dfrac{3}{4} =  \dfrac{3}{36} =  \dfrac{1}{12}

\text {Raisin left = } \dfrac{3}{4}  - \dfrac{1}{12} =\dfrac{9}{12}  - \dfrac{1}{12} = \dfrac{8}{12}  -= \dfrac{2}{3}

Answer: She has 2/3 of the package left.
