Question

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?

Answer 1

To find the amount of sugar Ms. Johnson used, we need to multiply the amount of sugar in the canister by 1/2.

1/2 * 7/8 = (1*7)/(2*8) = 7/16

Ms. Johnson used 7/16 cups of sugar when preparing the dessert.

Answer 4

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?(1 point)

Answer 5

To find the fraction of campers who play the guitar, we need to multiply the fractions representing the proportion of campers who play an instrument and the proportion of campers who play the guitar within that group.

Fraction of campers who play an instrument: 1/3
Fraction of those campers who play the guitar: 2/5

Fraction of campers who play the guitar = (1/3) * (2/5) = 2/15

Therefore, 2/15 of the campers at Rosewood Performing Arts Camp play the guitar.
