yolanda needs 5 pounds of ground beef to make lasagna for a family reunion. one package of ground beef weights 2 1/2 pounds. another package weights 2 3/5 pounds. how much ground beef will yolanda have left over after making the lasagna?

Respuesta :

We need to find the same denominator for 1/2 and 3/5...
It's 1/2= 5/10 , 3/5= 6/10

Then, 5/10 + 6/10 = 11/10 = 1 and 1/10

Now to add the whole numbers.

It's 2+2+1+1/10=5 1/10

She needed 5pounds of ground beef...

5 1/10 - 5 = 1/10 pounds

The answer: Yolanda has 1/10 pounds of ground beef left over.
