Talil is going to make some concrete mix. He needs to mix cement, sand and gravel in the ratio 1 : 3 : 5 by weight.

Talil wants to make 180 kg of concrete mix.

Talil has

15 kg of cement
85 kg of sand
100 kg of gravel

Does Talil have enough cement, sand and gravel to make the concrete mix?

Step-by-step explanation:

Cement : Sand : Gravel

1 : 3 : 5

Cement = 1/9 x 15 kg = 5/3 kg

Sand = 3/9 x 85 kg = 85/3 kg

Gravel = 5/9 x 100 kg = 500/9 kg

Concrete = Cement + Sand + Gravel

180 kg = 5/3 kg + 85/3 kg + 500/9

180 kg = 700/9 kg

180 kg = 85.55555556 kg

No,Talil does not have enough cement,sand and gravel to make the concrete mix.
