FRAME NUMBER 27
LEVEL C
Refer to FRAME NUMBER 25. In order to simplify setting up this problem, we mentally phrase
the verbal expression of this direct proportion. We say: "6 workmen are to X workmen as 1,800 articles
are to 2,700 articles." We write this as
6
1,800
=
or
or 6:X = 1,800:2,700. Complete the solution:
X
2,700
1,800X = 16,200
X=
NOTE: The same kinds are compared: "workmen are to workmen as articles are to articles."
