Lola has 4 1 2 cups of rice. she uses 3 4 of the rice to make sushi rolls for dinner. she uses the rest of the rice to make rice pudding for dessert. how much rice does lola use for the rice pudding?



Answer :

Lola used 15/4 or [tex]3 \frac{3}{4} [/tex] cups of rice for pudding.

Amount of rice Lola has = [tex]4 \frac{1}{2} [/tex] cups

Converting from mixed fraction to improper fraction

Amount of rice Lola has = (2×4 + 1)/2

Amount of rice Lola has = 9/2 cups

Now, to find the amount of rice used for rice pudding, we will simply subtract the rice left with her after being used for sushi rolls.

Amount of rice used for pudding = Amount of rice Lola has - Amount of rice used to make sushi rolls

Amount of rice used for pudding = 9/2 - 3/4

Performing subtraction to find the amount of rice used for pudding

Taking LCM we get 4

Amount of rice used for pudding = (9×2 - 3)/4

Amount of rice used for pudding = (18 - 3)/4

Amount of rice used for pudding = 15/4

In mixed fraction, the amount of rice used for pudding = [tex]3 \frac{3}{4} [/tex]

Hence, Lola used 15/4 or [tex]3 \frac{3}{4} [/tex] cups of rice for pudding.
