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
