To simplify 18 over 34, we need to find the greatest common factor (GCF) of both numbers, which is 2. Dividing both the numerator and denominator by 2 gives us 9 over 17. Therefore, 18 over 34 simplifies to 9 over 17 in its simplest form.
5 1/9 minus 2 5/6 can be solved by changing the 9 and 6 to a common denominator of 18. 5 2/18 minus 2 15/18 is your new problem. Now you need to borrow from the 5 to make 2/18 large enough to subtract 15/18. 4 20/18 minus 2 15/18 is your new problem. Now you subtract the whole numbers and then then numerators of the fractions. 2 5/18 is your answer.
(x + 2)(x - 9)
1 and 1 over 3
3 and 2/5 minus 1 and 1/3 = 2 and 1/15
17/18
17/18 minus 2/3 is 5/18
(17/18) - (2/9) = (17/18) - (4/18) = 13/18
3 minus 3/18 is 2 5/6
7/2 or 3.5
6/17 − 4/17 = 34/289 which simplifies to 2/17
16/18 - 9/18 = 7/18
5 over 18
7/18 - 5/18 = 2/18 = 1/9
5/6 + 2/18 = 15/18 + 2/18 = 17/18
4/-9 − 5/2 = -53/18 or -217/18
20 minus 17 minus 3 minus 2 equals -2
