FRAME NUMBER 6

LEVEL A

In a ratio, the first term and the second term are individually called the antecedent and the

consequent. Hence, when referring to a ration of4

(4:5), 4 is the

and 5 is the

5

.

LEVEL B

In a proportion

2 =

4 or 2:3 = 4:6, the first and fourth terms (2 and 6) are also

called the

3

6

extremes, and the second and third terms (3 and 4) are called the means of this proportion. Then, in a

proportion 5 = 10 or 5:6 = 10:12 (6 and 10) are then

and (5 and 12) are the

LEVEL C

Type 4. The distance between two points on a captured enemy map is 2.54 inches. The same

distance on a map in your possession, with a scale of 1:50,000 is 6.35 inches. What is the scale of the

enemy map? We phrase this: 1:X (enemy map) is to 1:50,000 (your map) as 2.54 inches is to 6.35

inches. We write

X

=

6.35. (Note that the second part of the equation is inverted

because the

50,000

2.54

smaller the number the larger the denominator of scale.) Complete the solution: 2.54X = 317,500.
