How many tons of cement, sand and stone do builders need to prepare 190 tons of concrete with 2:3:5 ratio of cement, sand and stone? emergency


190÷(2+3+5)=19
Cement = 2 × 19 = 38 tons
Sand = 3 × 19 = 57 tons
Stone = 5 × 19 = 95 tons
Do not understand can ask, help please adopt, thank you!



A kind of concrete is made of cement, stone and sand in the ratio of 2:3:5. Now there are 1400KG of cement, 1800 kg of sand and 3250 kg of stone on the construction site,
How many kilograms of this concrete can be mixed with these materials at most?


The existing ratio is 1400:1800:3250 = 28:36:65
2:3:5=28:42:70
So there's less sand
Up to 1400 △ 2x (2 + 3 + 5) = 7000 kg

There are 1400KG of cement, 1800kg of sand and 3250kg of stone on the construction site. A: with these materials, about 2.2.7m3 of concrete can be mixed at most. (assuming 180 kg of water is taken in each cubic meter)
