What's the answer to all of these problems. i get the concept kinda but i always get the wrong answers i need to know the right ones so i can compare.

If you like my answer please give me the brainliest answer! :)

a) We must convert 3 3/4 into an improper fraction (a fraction where the numerator, the number above the line, is bigger than the denominator, the number below the line) and we do this by multiplying the denominator by the whole number 3 and then adding the numerator.
So: 4 × 3 + 3 = 15/4 . >> Now we must multiply the numerator by 5 so: 15 × 5 = 75/4. >> We can simplify this to 8 3/4 pounds of birdseed!

b) We convert 1 1/2 to improper fraction = 3/2 . We then multiply this by 2 to get 6/4. Now we must divide 75/4 by 6/4 = 12 bags (but with 3/4 pounds left over).

c) Yes, because when we divided 75/4 by 6/4, we had 3/4 pounds left over, which couldn't fit into a bag because it wasn't 1 1/2 pounds.
