Answer:
436
Step-by-step explanation:
let take x = extra men would he employed
months. men
9. 560
7. x
cross multiply *<- this is the symbol for multiply.
(9*x) = (560*7)
9x. = (3920)
x. = 3920/9
[ / <- this slash is the symbol of division]
x. = 435.5555555556
round it
x. = 436
560 - 436 = 124
therefore,
124 extramen would he employed.
