There are 7/8 cups of sugar in a canister in the kitchen. Ms. Johnson used 1/2 of the sugar when she was preparing dessert for her daughter's birthday cake. How much sugar did she use? Show your work.
To find how much sugar Ms. Johnson used for the dessert, you need to multiply the 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 for the dessert.
To find out how much sugar Ms. Johnson used, we need to multiply the total amount of sugar in the canister by the fraction representing the amount she used.
The total amount of sugar in the canister is 7/8 cups.
Ms. Johnson used 1/2 of the sugar, so we multiply the total amount by 1/2:
(7/8) * (1/2) = (7 * 1) / (8 * 2) = 7/16
Therefore, Ms. Johnson used 7/16 cups of sugar when preparing dessert for her daughter's birthday cake.
