There are 78
cups of sugar in a canister in the kitchen. Ms. Johnson used 12
of the sugar when she was preparing dessert for her daughter's birthday cake. How much sugar did she use?(1 point)
To find out how much sugar Ms. Johnson used, we need to multiply the total amount of sugar in the canister by the fraction she used.
1/2 * 7/8 = (1 * 7)/(2 * 8) = 7/16
Therefore, Ms. Johnson used 7/16 cups of sugar when preparing the dessert.
To determine how much sugar Ms. Johnson used, we need to find the product of the fraction representing the amount of sugar in the canister and the fraction representing the portion of sugar she used.
First, let's convert the fraction 7/8 to a mixed number:
7 divided by 8 equals 0 remainder 7.
Therefore, 7/8 can be written as 0 7/8.
Next, let's multiply the mixed number 0 7/8 by the fraction representing the portion used, 1/2.
To multiply mixed numbers by fractions, we need to convert the mixed number to an improper fraction:
0 7/8 can be rewritten as (0 * 8 + 7) / 8 = 7/8.
Now that we have the improper fraction representing the amount of sugar in the canister, we multiply it by the fraction representing the portion used:
(7/8) * (1/2) equals (7 * 1) / (8 * 2) = 7/16.
Therefore, Ms. Johnson used 7/16 cups of sugar when preparing the dessert for her daughter's birthday cake.
To find out how much sugar Ms. Johnson used, we need to multiply the fraction of sugar used (1/2) by the total amount of sugar in the canister (7/8).
First, let's convert the fractions into decimals: 1/2 = 0.5 and 7/8 = 0.875.
Now we multiply 0.5 by 0.875: 0.5 * 0.875 = 0.4375.
So, Ms. Johnson used 0.4375 cups of sugar for the dessert.
