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?
4 1/2-3/4
9/2-3/4
=15/4
=3 3/4
To find out how much rice Lola uses for the rice pudding, we need to subtract the amount of rice she used to make the sushi rolls from the total amount of rice she has.
Lola has 4 1/2 cups of rice, which can be written as 4 + 1/2.
To add the whole number, 4, and the fraction, 1/2, we need to find a common denominator. The least common denominator for 2 and 4 is 4.
Now, let's convert the whole number, 4, into a fraction. Since there are 4 parts of 1/2 in 4, we can write it as 4/1.
Adding 4/1 and 1/2, we get:
4/1 + 1/2 = 8/2 + 1/2 = 9/2
So, Lola has a total of 9/2 cups of rice.
Next, Lola uses 3/4 of the rice to make sushi rolls. To find out how much rice she uses for the rice pudding, we need to subtract 3/4 from 9/2.
To subtract fractions, we also need a common denominator. The least common denominator for 4 and 2 is 4.
Now, let's convert 9/2 into a fraction with denominator 4:
9/2 = (9/2) x (2/2) = 18/4
Now, subtracting 3/4 from 18/4:
18/4 - 3/4 = 15/4
Therefore, Lola uses 15/4 cups of rice for the rice pudding.
To find out how much rice Lola uses for the rice pudding, we need to subtract the amount of rice she used for making sushi rolls from the total amount of rice she had.
Total amount of rice Lola had = 4 1/2 cups
Amount of rice used for sushi rolls = 3/4 of 4 1/2 cups
To calculate 3/4 of 4 1/2 cups, we can multiply the whole number, 4, by 3/4 and add it to the result of multiplying the fraction, 1/2, by 3/4.
4 * 3/4 = (4 * 3) / 4 = 12/4 = 3
1/2 * 3/4 = (1 * 3) / (2 * 4) = 3/8
Adding the results together:
3 + 3/8 = 24/8 + 3/8 = 27/8
So Lola used 27/8 cups of rice for sushi rolls.
Now, we can find out how much rice Lola used for the rice pudding by subtracting the amount used for sushi rolls from the total amount of rice Lola had.
Total amount of rice Lola had = 4 1/2 cups = (4 * 2 + 1) / 2 = 9/2 cups
Amount of rice used for sushi rolls = 27/8 cups
Subtracting:
9/2 - 27/8 = (9 * 4 - 27 * 2) / (2 * 8) = (36 - 54) / 16 = -18/16 = -9/8
Since we cannot have a negative amount of rice, it seems like there was an error in the calculations. However, if we assume that Lola did not use more rice for sushi rolls than what she had, it means that she used all the remaining rice for the rice pudding.
Therefore, Lola used 0 cups of rice for the rice pudding.
