To factor the expression, we need to find the gcf of 44,55 and 11.
In this case, the gcf is 11. so we could write the expression as...
11(4x+y+5z)
Explanation-
3/7 is not proportional because if you divide 3 by 7 you don’t get a whole number or nice fraction
8/28 is proportional because if you divide the fraction by 4 you get 2/7 which is a nice fraction
A fraction. Thats the answer ;)
