First, let's make 1/2 and 3/7 have the same denominator to make it easier to see. We know that there Least Common Multiple (LCM) is 14.
1/2=7/14
3/7=6/14
Wait a second... 3/7 is less than 1/2. This means that Winnie's statement is false because it is impossible that after adding more flour, she actually has less flour than what she started with.
Hope this helps! :)
False because it is only showing the quarter
Answer:
31/40
Step-by-step explanation:
Find a common denominator
2/5= 16/40
3/8= 15/40
16/40+15/40= 31/40
The answer would be D if it was 250-6-3n. it wouldnt be A or C because 9 isnt anywhere in the problem and it wouldnt be B because she used 6 peices of paper she didnt just give it to her students
