FRAME NUMBER 28
LEVEL C
Refer to FRAME NUMBER 26. In phrasing the verbal expression of this inverse proportion, we say: "6
workmen are to 15 workmen as 10 days are to X days." This is normally written
6 = 10 or 6:15 = 10:X but since an increase in one quantity causes a decrease in another quantity
15 X
this is an inverse proportion and one side of the equation must be inverted. Hence, it is written
6 = 10 or 6:15 = 10:X,
15 X
Complete the solution:
15X = 60
X=
5
