$28$ Answer
B
$36$
C
$98$
D
$14$

Answer

There are

28

senior specialists on the team.

The correct answer is found by first adding the components of the ratio (

7 + 2 = 9

) to represent the entire task force. Next, divide the total number of members (

126

) by

9

to determine that each ratio 'part' equals

14

members. Finally, multiply this unit value by the

2

parts that represent the senior specialists (

14 \times 2 = 28

Step-by-Step Solution

Determine the total number of parts in the given ratio.

7 + 2 = 9

total parts.

To find the value of a single part relative to the entire group, you must first know how many equal parts make up the whole.

Calculate the numerical value of one single part.

126 \div 9 = 14

members per part.

Dividing the total number of members by the total ratio parts gives the quantity represented by one unit.

Multiply the value of one part by the number of parts designated for senior specialists.

14 \times 2 = 28

senior specialists.

The ratio states there are

2

parts of senior specialists for every

7

parts of junior analysts.
