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?(1 point)
To find out how much sugar Ms. Johnson used, we need to calculate 1/2 of 7/8 cups.
To do this, we multiply 7/8 by 1/2:
(7/8) * (1/2) = (7 * 1) / (8 * 2)
= 7/16
Ms. Johnson used 7/16 cups of sugar.

One-third of the campers at Rosewood Performing Arts Camp play an instrument. Two-fifths of those campers play the guitar. What fraction of the campers at Rosewood Performing Arts Camp play the guitar?
To find the fraction of campers at Rosewood Performing Arts Camp that play the guitar, we need to multiply the fractions representing the proportion of campers who play an instrument and the proportion of those who play the guitar.
