28 in this case.
28
Divide 28 by 4. X = 7
Divide it by 4 and so a 1/4 of 28 is 7
You need to divide it by 6/7.
What the question is really asking is: 4 x ? = 28 To find '?', you divide 28 by 4. 28 / 4 = 7 ? = 7 4 groups of 7 equal 28.
divide both sides by 7 28/7 = 4 35/7 = 5 28/35 = 4/5 four fifths
