Question

27% of a fertilizer is superphosphate. How much superphosphate (in kg) is in 2 tonnes of the mixture?

Answer 1

we have that 27% of a fertilizer is superphosphate, hence we will have that value multiplied by 1000 and by 2, because we are considering 2 tonnes. Hence, we will get, in one fertilizer, 27%, which is equal to 27g = 0.0027kg, which we can say it is the same as 0.00027 tonnes, and this is equal to 0.27kg.
