Question

Eddie is fishing he has one and 1/4 ounce of weight on his line but his bait isn't getting to the bottom of the lake Eddie add another 1/2 ounce weight to the line but it's still not enough finally Eddie at eight 3/4 ounce weight and the big things how much weight does now have on his line

Answer 1

He starts with 1 and 1/4 then he adds 1/2 then he adds 8 3/4:
1 1/4+1/2+8(3/4)=X.
Multiply: 8(3/4)= 8/1•3/4= 2/1•3/1=6/1=6.
Add: 1 1/4+1/2 or 2/4=1 and 3/4+6=7 and 3/4.
He now has 7 and 3/4 ounces :)
