John had 2⁄3 of his homework complete, sarah had 5⁄10, alex 7⁄8, and michelle 1⁄2. who completed the most of the homework assignment? a. sarah b. michelle c. alex d. john

Hey there!

So, when finding who completed more, we would want to find the lowest denominator, but also, we would have to compare it with the numerator.

John: He completed 2/3, which is basically almost done.

Sarah: She only completed (half) of her homework.

Alex: He only did 7/8

Michelle: He/she only did 1/2, which is only half.

So, from looking at these fractions above, Michelle and Sarah are out.

We would just have to determine, which is finished more, John or Alex.

John had 2/3 & Alex 7/8

So, by comparing them both, 7/8 would be greater because the smaller the denominator is, and the closer that the numerator is to the denominator, this would mean that the homework is almost finished.

Your correct answer is Alex, he has completed more.

Hope this helps you!
