Question

At a butcher​ shop, Hilda bought 6 1/4 lb of Beef and some pork. She left with 13 1/20 lb of meat. Express the number of pounds of pork she bought using a decimal so Hilda bought ? lb of pork

Answer 1

Hilda bought 6 1/5 pound of pork

As a decimal 6.2 pounds of pork

Explanation:

Make the denominator of 6 1/4 equivalent to ?/20

1/4 = ?/20

Multiply numerator and denominator by 5

5/20

So the amount of beef she bought would be 6 5/20

Change both fractions to an improper fraction

6 5/20 = 125/20 13 1/20 = 261/20

Subtract 125/20 from 261/20

261/20 - 125/20 = 136/20

Remember to keep the denominator the same.

Turn 136/20 to a proper fraction by dividing 20 from 136

136/20 = 6 8/20

Simplify

6 8/20 = 6 1/5

Answer 2

Hilda bought 15.11 lb of pork.

Explanation:

Cost of Beef that Hilda bought = 4 17/20 = 4.85 lb

Cost of the total meat she bought = 19 24/25 = 19.96 lb.

To find the number of pounds of pork she bought, subtract.

Number of pounds of pork she bought = 19.96 - 4.85 = 15.11 lb.
