spayn [35]

Answer:

$\large\boxed{32\ is\ 90\%\ of\ 35\dfrac{5}{9}}$

Step-by-step explanation:

<h3>METHOD 1:</h3>

$\begin{array}{ccc}32&-&90\%\\\\x&-&100\%\end{array}\qquad\text{cross multiply}\\\\\\90x=3200\qquad\text{divide both sides by 90}\\\\x=\dfrac{3200}{90}\\\\x=\dfrac{320}{9}\\\\x=35\dfrac{5}{9}$

<h3>METHOD 2:</h3>

$\begin{array}{cccc}32&-&90\%&\text{divide both sides by 9}\\\\\dfrac{32}{9}&-&10\%\end{array}\\\\\\90\%+10\%=100\%\to32+\dfrac{32}{9}=32+3\dfrac{5}{9}=35\dfrac{5}{9}$

Mr. Greg had 8 sandwiches. He gave 1/4 to Nehamiah, 1/4 to Elijah, and 1/4 to Elizabeth. How many sandwiches did Mr. Greg have l

SVEN [57.7K]

There are many ways to work this out. One way could be:

Add up:
1/4 + 1/4 + 1/4 = 3/4

Find 3/4 of 8 so;
8 / 4 = 2
2 x 3 = 6

Find what's remaining:
8 - 6 = 2

So Mr.Greg has sandwiches left.
Hope it helped :)
