Step-by-step explanation:
7 8/5-3 4/5
If Kalon can complete the job in 4 hours, he has completed 1 5/7 over 4 of the job if he works together with Marna. Letting x be the number of hours it will take Marna to work alone, she has completed 1 5/7 over x of the job. The amounts of job they have done should be equal to 1.
(1 5/7 / 4) + ( 1 5/7 / x ) = 1
The value of x is 3. So, Marna can clean the chimney in 3 hours.
It must be an equation in order to be solved for example, 3x+5=11 then x would be 2
It's easiest to simplify all these ratios to 5:8 - 1:15 - 2:5 - 3:8 - 2:5 - 5:8 - 3:8 -2:5 - 1:15 - 3:8 - 5:8 - 3:8. Now all you have to do is match them up.
