Ellie uses 12.5 pounds of potatoes to make mashed potatoes. she uses one-tenth as many pounds of butter potatoes. how many pounds of butter does ellie use?

You would divide 12.5 by 10 and then you have how much butter was used

1/10 would be .1 as a decimal, so you would need to do 12.5 divided by .1, which would be just moving the decimal point in 12.5 one space to the right, making the answer 125. Hoped it helped ; )
