Answer:
Ok so first you would have to turn them into improper fractions which is
3 
= 
and 4 
= 
So now that you have made them both improper fractions you have to find common denominators.
To find common denominators you must multiply both the numerator and the denominator by the same thing. Since your oposing fraction has a denominator of 5 you can know that a even number wont go in an odd number so take and mutiply both numbers by 2 and get 
. Then mutiply both numbers in by 5 to get a common denominator.
=35 - 44 = -9 so your answer is 
Step-by-step explanation:
Answer:
The time required to finish the work by both candy and Tim working together = 36.83 minute
Step-by-step explanation:
Time taken by the candy to finish the work 
= 85 min
Time taken by the Tim to finish the work 
= 65 min
Thus the time taken by both to finish the work = 
Put the values of and we get ,
= 
= 
= 36.83 minute
Thus the time required to finish the work by both candy and Tim working together = 36.83 minute
(-2 + 0.8) ÷ (1²-1.3) =
(-1.2) ÷ (1-1.3)
(-1.2) ÷ (-0.3)
= 4
