Question

A chemist is using 382 milliliters of a solution of acid and water. If 15.4% of the solution is acid, how many milliliters of acid are there? Round your answer to the nearest tenth.

Answer 1

58.8

Explanation:

basic facts:

-15.4% is the same as 15.4/100

- the word 'of' in maths means times

so 15.4% of the 382ml is the same as

382*15.4/100

to do that, you multiply 382 by 15.4 = 5882.8

then you divide that by 100= 58.828

and then you just round that of to 58.8
