Susie has 8 over 9cup of ice cream. How many 1 over 4cup servings can she make?

Question

Mercury · Answer

# of servings = (total amount of ice cream) / (amount per serving)

so in your case, you have a fraction divided by a fraction:

$$\frac{ \frac{ 8 }{ 9 } }{ \frac{ 1 }{ 4 } }$$

to simplify this, take the fraction in the denominator (1/4), switch the numerator and the denominator (so switch the 1 and the 4) and change the division operation to a multiplication operation. then, multiply the two fractions as normal (numerator * numerator) / (denominator * denominator)
