6 3/5 - 4 3/4?

This is pretty simple. First, you want to make the denominators the same, to make things easier. So find the LCM (Least Common Multiple), which is 20 in this case, and then multiply the 5 by 4 (to get 20) and vice versa for 4. Dont forget to multiply the numerator the same way. Now you should get something easier:

6 12/20 -4 15/20.

Now in this case, you must borrow a whole to finish this problem. So borrow a whole number from 6, (making it a 5) and bring it to the first fraction of the equation.

5 32/20 - 4 15/20.

Now, just solve. You should get  1 17/20. This cannot be simplified.

Kaylis [27]

Your question was incomplete. Please refer the content below:

Washington high school's head tennis coach, Ms. racket, runs a tennis camp for middle school students every summer. the students bring their own lunches, but Ms. racket provides them with snacks. there is a proportional relationship between the number of students who enroll in Ms. racket's tennis camp, x, and the total number of snacks she buys, y. what is the constant of proportionality? write your answer as a whole number or decimal. snacks per student.

X      Y

10     30

13     39

14     42

21     63

The constant of proportionality is 3 as for 1 student she buys 3 snacks.

The constant of proportionality means the ratio between the terms x and y.

It is calculated by dividing y by x.

Here we get that:

X      Y           constant of proportionality(Y/X)

10     30                               3

13     39                               3

14     42                               3

21     63                               3

Therefore, we get the constant of proportionality as 3.
