Answer:
11
Step-by-step explanation:
Change 2 3/4 to a mixed number.
11/4
Then multiply
11/4 • 4
Get rid of common denominators. Which are the 4s.
So you're left with 11.
Or you could just turn 4 into 4/1.
Which would be 44/4.
Which simplifies to 11.
Hope this helps.
cheap answer is, you <u>multiply one fraction by the other's denominator</u>, so let's do that with both of these fellows.
