Demont made one fourth pound of rock candy.He will separate the candy into four stacks.If he puts an equal amount of candy in ea
kondor19780726 [428]

Answer:

1/16

Step-by-step explanation:

Demont made one fourth (\frac{1}{4}) pound of rock candy

He separates the candy into four sacks equally.

This is done by dividing the total fraction of candy of a pound of candy made  by the number of sacks

The fraction of a pound of candy that will be in each sack therefore is:

\frac{1}{4}\div  4= \frac{1}{4}X\frac{1}{4}=\frac{1}{16}

Therefore, One-Sixteenth of a pound of candy will be in each of the sack.

Mashutka [201]

Answer:

250 students

Step-by-step explanation:

Given data

Let the total number of students be x

Number of students that plays instrument = 10

Hence

40% of x = 10

40/100*x= 100

0.4x=100

x=100/0.4

x= 250

Hence there are 250 students in total
