At a butcher shop, Hilda bought 6 9/20 lb of beef and some pork. She left with 17 17/25 lb of meat. Express the number of pounds of pork she bought using a decimal.

56.15

Step-by-step explanation:

First, convert    lbs to a decimal. Multiply the main number (6) by the denominator (20) and then add that number to the numerator (9). The number you will get will be (6 x 20)+9 = 129. 129 is now the new numerator as an improper fraction so the improper fraction is now .

Now make lbs an improper fraction. It would be .

Now subtract the amount of pork from the total amount of meat. - . Find a common denominator. I'm going to use 500, although there might be something less.

is the result. Now you can either start dividing or simplify the fraction, which hopefully you already know how to do. 5615 ÷ 100 = 56.15

Really hope this helped, I tried explaining well! Ask more questions if you need!

it would take 7/10 of an hour too fill the pool.
