Sally brought a 1 quart container of buttermilk to make pancakes. Her recipe says to use 1/2cups Of butter milk for 3 pancakes.
GrogVix [38]

Answer:

24

Step-by-step explanation:

Quart is a volume unit, equal to a quarter of a gallon. The symbol is "qt"

A quart container is equivalent to 4 cups.

a pancake need only 1/2 cup of butter milk.

We use a rule of three.

if 1/2 cup can make 3 pancakes.

How many pancakes 4 cups can make?

\frac{4*3}{\frac{1}{2} }=24

We only have to multiply the 4 cups of butter milk by the 3 pancakes and the divide it by the 1/2 cup you need to make only 3 pancakes.

!!25 POINTS AND BRAINLIEST!! A recipe calls for 2 cups of pizza sauce. I only want 3/4 OF the full 2 cups. How will I figure out
Nutka1998 [239]

Mathematical Answer: 2cups*3/4 = 1 and 1/2 cups or 1.5 cups.

How to do it while cooking:

  1. Get out a container large enough to hold at least 4 cups sauce
  2. Get out a "1 cup" and "1/2 cup" measuring cup.
  3. Measure out 1 cup of sauce with the "1 cup" measuring cup.
  4. Measure out  1/2 of a cup of sauce with the '1/2 cup' measuring cup.
  5. pour both cups into the larger container.

And there you go you have 3/4 of 2 cups of sauce.
