Five tons of cement, yellow sand and stones are mixed into concrete with the ratio of cement, yellow sand and stones of 5:3:6. If the cement is just used up, will yellow sand and stones be enough? If not, how many tons less? If so, how many tons more?

Five tons of cement, yellow sand and stones are mixed into concrete with the ratio of cement, yellow sand and stones of 5:3:6. If the cement is just used up, will yellow sand and stones be enough? If not, how many tons less? If so, how many tons more?

Using cement as the benchmark: 5 tons of cement is 5 parts, then each part is: 5 △ 5 = 1 (ton), cement: 5 - (1 × 5) = 0 (ton), yellow sand: 5 - (1 × 3) = 5-3 = 2 (ton), stone: (1 × 6) - 5 = 6-5 = 1 (ton), & nbsp; a: if the cement is just used up, there will be 2 tons of yellow sand left and 1 ton of stone left

A kind of concrete is prepared according to the ratio of 2:4:5 of cement, stone and sand. At present, there are 3.5 tons of cement, stone and sand respectively. How much can be prepared at most

Female Superman YSM,
The first floor answer is wrong!
Because the ratio of cement, stone and sand is 2:4:5, the sand can only be used up when the mixture is most
Maximum preparation: 3.5 △ 5 × (2 + 4 + 5) = 7.7 (ton)
