Im confused can someone please explain how to do this

ozzi

First rewrite the mixed number as an improper fraction:

-1 1/14 = -15/14

Now you have :

-3/7 / -15/14

When dividing by a fraction, flip the second fraction over and change divide to multiply:

-3/7 x -14/15

Now multiply top by top and bottom by bottom:

(-3 x -14) / ( 7 x 15) = 42/105

Simplify by diving each number by 21 to get the final answer :

2/5

alekssr [168]

Answer:

84 students

Step-by-step explanation:

See the attached table

As shown there are 20 students from Math club, 7 of them would like to choose calculators.

so, the probability of students who choose calculators = 7/20

If there are 240 students in the Math club

So, the number of students expected to choose calculators = 240 * 7/20

So, the number of students = 84 students
