Here is the answer to the problem above. So, if the monthly income is $300 and $50 was spent on clothing, we will find the percentage of $50 from $300 by dividing 50 by 300 then multiply the quotient by 100. So the answer is 16.67%. So the answer is 16.67%. Hope this answers your question.
1/3 is 3/3 so 300/3 is 100 so 2/3 is 200 ml more so it holds 500 ml
