How do I calculate the change in mixed numbers

You must turn all of the mixed numbers into improper form. Then you subtract

Step-by-step explanation:

1) Multiply the denominator with the number

2) Take the product and add it to the numerator

*congratulations, you made an improper fraction*

3) Repeat steps 1 and 2 for your next mixed number

4) Make sure the denominator is set equal to each other

5) Subtract fractions like normal

if you explain the the question more correctly i might be able to answer this better

step-by-step explanation:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
