Subtract. 5/7−2/5

Enter your answer as a fraction in simplest form by filling in the boxes.

11/35

Step-by-step explanation:

Make the denominator the same and subtract

5/7 turns into 25/35 and 2/5 turns into 14/35 that gives you 11/35

5/7-2/5= 11/35

You need to make them have the same second half, so u get them to the least common factor of 7 and 5 which is 35. you would multiply 5/7 by5

5/7 x 5 = 25/35

And you would multiply 2/5 by 7

2/5 x 7 = 14/35

Then you would subtract 25/35 by 14/35

25/35 - 14/35 = 11/35

This is simplified as much as it can be, because 11 is a prime number so u would have to be able to divide 35 by 11 which does not come out as a whole number so u cant do that for a fraction causing it to stay as 11/35

35 is an outlier

step-by-step explanation:

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
