A bah of oranges weighs 5 1/4. How much does 1 1/2 weigh?(that's the question my question is do we add, subtract, multiply or divide plzzzzzzzzz help meeeeee im new to this website =)

What is 1/2 of 5 1/4?

Once you find that answer (call it x), add it to 5 1/4. Then you'll know what one and a half bags of oranges weigh.

It's MUCH easier if you convert those fractions to decimals:
5.25*0.5 = x
then 5.25 + x = ??
