Answer 1

Explanation:

You could change all the fractions so that they have the same denominator (bottom number) and then compare the numerators (top numbers) or change the numbers to decimals to compare them (divide the top number by the bottom number)

0 is 0/6 is 0.000

1/6 is 0.166

1/2 is 3/6 is 0.500

Maybe you can see that 1/6 is closer to 0 than to 1/2

3/7 is 0.42857 is pretty close to 3/6 which is 0.50000, right, that is 1/2.

So, rough estimate, the person spent 0 hrs + 1/2 hr

organizing...total= 1/2 hr
