Answer: Here’s one I made up! Combined, Megan and Kelly worked 60 hours, Kelley worked twice as many hours as Megan. How many hours did they each work? Hope this helps!
If she has 10/12 and uses 8/12 then you just subtract. Since the denominators are the same you just subtract 10-8 and get 2 the denominator is the same for your answers and so it is 2/12
