Help please what is 6 -7/9

47/9      

5.22222  

Step-by-step explanation:

    6 =  6/1 = 6 .9/ 9

         Equivalent fraction: The fraction thus generated looks different but has the same value as the whole

Common denominator: The equivalent fraction and the other fraction involved in the calculation share the same denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

6 . 9 - 9 (7 )/9 = 47/9

problem:

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

f(5/2) = 10/3

i hope this !
