Tony is pouring milk for student lunches. She knows that 3 quarts of milk contain 12 cups. How many cups can she pour with 7 qua
Evgesh-ka [11]

Answer:

7 quarts = 28 cups

10 cups = 2.5 quarts

Step-by-step explanation:

In order to solve the two different questions in the problem, starting with a ratio of the number of quarts to the number of cups would be helpful:

\frac{quarts}{cups}=\frac{3}{12}=\frac{1}{4}

So, for every 1 quart of milk, she can pour 4 cups.  Using this ratio, we can set up equivalent ratios, or proportions, to solve for the missing value.  For the first question, we need to know that amount of cups in 7 quarts:

\frac{1}{4}=\frac{7}{x}

We can solve for 'x' by multiplying the numerator and denominator by the same factor, in this case '7'.  So, 4 x 7 = 28 cups.

Next, we need to solve for the amount of quarts needed for 10 cups:

\frac{1}{4}=\frac{x}{10}

4 x 2.5 = 10, so we need to multiply the numerator by 2.5: 1 x 2.5 = 2.5 quarts.

Eight members of the Math club equally shared three pizzas. Expressed as a fraction,whAt part of a pizza did each member receive
Vera_Pavlovna [14]
3/8 of a pizza.

If you divide each pizza into eight parts, each member would receive 1/8 of one pizza. Since there are three pizzas, each member would receive three 1/8 of a pizza, or 3/8.

You can prove this answer by multiplying 3/8 by 8, to get 24/8 simplified to 3.
