can someone help me with this question..thx

Only if the rate is equal for all men

pls send options as well simply adding with values would give us around 1 only..

yes, it 1. so just simply add the values without combining any of the three fractions... like Common denominator? I guess I over-complicated it

Damian needs a of the wood in the shed on theffirst day and % of the remaining wood on the second day to make a tree-house in his backyard. Given that 2⁄5 of the wood in the shed is unusable due to fungal damage what fraction of usable wood is left once he has completed the tree-house? Answer is 11/36 but how? Damian needs 1/4 of the wood in the shed on the first day and 2/9 of the remaining wood on the second day to make a tree-house in his backyard. Given that 2/ 5 of the wood in the shed is unusable due to fungal damage what fraction of usable wood is left once he has completed the tree-house?

yes, but idk if such approximation and addition ques would come in the exam..

solved it.. very tricky for some reason i just hate typing all this.. so a photo:) pls tell the difficulty level also

there’s a slightly shorter route also

Pure algebra will lead to a time consumption. Let’s take some assumption here. I see a 1/4, a 2/9, and a 2/5....4*9*5 = 180. So let’s assume the total amount of wood is 180 kgs. Wood Damian needs on first day = (1/4) * 180 = 45 kgs Remaining Wood = 180 - 45 = 135 kgs Wood Damian needs on second day = (2/9) * 135 = 30 kgs Total wood used = 45 + 30 = 75 kgs Unusable wood = (2/5) * 180 = 72 kgs Total Available Wood = 180 - 72 = 108 kgs Wood used = 75 kgs Usable Wood Left = 108 - 75 = 33 kgs Fraction = 33 / 108 = 3 / 35

yes i thought about taking LCM as well
