Question

Amy estimated that she spent 1/7 of her time on both math and science homework. Without doing any calculations determine whether or not Amy's estimate is accurate and explain why or why not.

Answer 1

Assuming that those were the only 2 things she was doing, then the answer is that her estimate is inaccurate, as 1/7 + 1/7 = 2/7

This does not equal the 1 we are looking for, with 1 representing 100%, or 7/7

Answer 2

Oh I did this question before so I know the whole problem ok, Amy’s answer is not accurate because they were supposed to add 1/4 plus 1/3 and u had to find the common denominator for the two fractions first. Because u can’t add the two fraction just like that u have to find the common denominator first. Hope this helps!!!!!!!!!!!!!!!! ; )
