Question

The cafe where you work just ran out of coffee you are at the store to buy 1 1/2 pounds of coffee. You have to put a can with 3/4 pound of coffee into your shopping cart. How many more pounds do you need

Answer 1

3/4

Explanation:

I'm not very good at understanding word problems but I'll try to help using the info I already have.

You bought 3/4 pounds and you need a total of 1 1/2 pounds.

Find the common denominator which in this case is 4. Multiply 1 1/2 by 2/2 to get 1 2/4

You leave 3/4 alone because the denominator is already 4.

Convert 1 2/4 to a mixed number by taking away the 1 and adding 4 to the numerator leaving you with 6/4

6/4 - 3/4 = 3/4

Therefore you need 3/4 pounds left

Hope I helped
