Answer:
3/4
Step-by-step 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
