Answer 2

Answer:

9

Step-by-step explanation:

if 6 men/14 days than, x men/21 days [set-up as a proportion problem]

6 men/14 days = x men/21 days [set the ratios equal to each other and cross-multiply]

(6)(21)=14x

126=14x [solve for x]

 

x=9

checking:

6 men/14 days = 9 men/21 days

126=126 [checks out]
