How many 1/4 cup servings of raisins are in 7/8 cups of raisins?

Ostrovityanka [42]

Answer:

Step-by-step explanation:

Divide 7/8 by 1/4. (You divide the "supply" of raisins into 1/4 cup "parts".)

$\frac{7}{8} \div \frac{1}{4} = \frac{7}{8} \times \frac{4}{1} = \frac{28}{8} =\frac{7}{1} =7$

Multiply 7/8 by the reciprocal of 1/4 ("flip" the 1/4).

The result is 28/8, which can be simplified ("reduced") to 7.
