You have to get the same common denominator, 9x2 is 18, so 7x2 is 14. 14/18-5/18 is 9/18. 9/9 is 1 and 18/9 is 2, so you are left with 1/2

CorrectFor instance, 2 + 5 + 9 +14 = 7 + 9 + 14 = 16 + 14 = 30(2 + 5) + (9 + 14) = 7 + 23 = 302 + (5 + 9) + 14 = 2 + 14 +14 = 16 + 14 = 302 + (5 + (9 + 14)) = 2 + (5 + 23) = 2 + 28 = 30

Get a common denominator (14), so you have (10 6/14 ) - (5 7/14). Since 7/14 > 6/14, borrow a 1 from the 10:1 = 14/14, so you have (9 20/14) - (5 7/14). Subtract the fractions and subtract the whole numbers: 413/14
That's probably "quotient." 9 x 2 - 14/7 = 18 - 2 = 16

4, yes. 5, 7, 9, 14, no.

You have to find the average of the two fractions. 4/7 + 5/7 = 9/7 (9/7) / 2 = 9/14 OR You can say 4.5/7 = 0.6428571428571... convert that to a fraction and reduce and you get 9/14
Yes 5/7 =10/14 which is larger than 9/14
CorrectFor instance, 2 + 5 + 9 +14 = 7 + 9 + 14 = 16 + 14 = 30(2 + 5) + (9 + 14) = 7 + 23 = 302 + (5 + 9) + 14 = 2 + 14 +14 = 16 + 14 = 302 + (5 + (9 + 14)) = 2 + (5 + 23) = 2 + 28 = 30
So 9/14 + 5/(-14) = 9/14 - 5/14 = 4/14 = 2/7
