Answer:
10
Step-by-step explanation:
10 workers working 2 hours a day is 2*10=20 work hours per day
2 workers working 5 hours a day is 2 *5=10 work hours per day
Per day 1/2 as many work hours so will take 2 times as long.
5*2 = 10 days
f = 4/5
explanation
f(10) = 8
so you divide both sides by ten in order to isolate the variable
10f/10 8/10
you now have
f = 8/10
simplify 8/10 to get
f = 4/5
hopefully i explained it well :)
