There is 7/8 quarts of orange juice. Mrs. Mathewson would like to serve her guests 3/16 quarts orange juice. How many guests can

kotegsom [21]

Answer:

$4\frac{2}{3}$ guests.

Step-by-step explanation:

We have been given that there are 7/8 quarts of orange juice. Mrs. Mathewson would like to serve her guests 3/16 quarts orange juice.

To find the number of guests Mrs. Mathewson can serve with 7/8 quarts of juice, we will divide 7/8 by 3/16 as:

$\text{Number of guests Mrs. Mathewson can serve}=\frac{7}{8}\div\frac{3}{16}$

Convert to multiplication problem by flipping the 2nd fraction:

$\text{Number of guests Mrs. Mathewson can serve}=\frac{7}{8}\times\frac{16}{3}$

$\text{Number of guests Mrs. Mathewson can serve}=\frac{7}{1}\times\frac{2}{3}$

$\text{Number of guests Mrs. Mathewson can serve}=\frac{14}{3}$

$\text{Number of guests Mrs. Mathewson can serve}=4\frac{2}{3}$

Therefore, Mrs. Mathewson can serve orange juice to $4\frac{2}{3}$ guests.

The cost of a pair of ice skates went from $200 to $140. What is the percent change in the cost of skates?

dmitriy555 [2]

so the pair went down from 200 to 140, so the difference is 200 - 140 = 60.

so if we take 200 as the 100%, what is 60 off of it in percentage?

$\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 200&100\\ 60&x \end{array}\implies \cfrac{200}{60}=\cfrac{100}{x}\implies \cfrac{10}{3}=\cfrac{100}{x}\implies 10x=300 \\\\\\ x = \cfrac{300}{10}\implies x = 30$
