Set it up this way: 8n + 7 = 2n Take 7 away from each side. 8n = 2n - 7 Take 2n away from each side 6n = -7 Divide each side by 6 n = -7/6 To check the answer, replace the n's with -7/6. 8 X -7/6 + 7 = 2 X -7/6 -56/6 + 42/6 = -14/6 -14/6 = -14/6

Well, honey, 196 can be divided by 1, 2, 4, 7, 14, 28, 49, 98, and 196 itself. So take your pick and have a blast dividing away!
40 / 11 simplified is 33 7/11ths 40 divided by 11 gives us 3 with a remainder of 7. So the whole number portion of our answer is 3, and the fractional portion is 7/11.
3/11+(-7/9) = -50/99

2. there couldn't be anything else because 100-98=2. don't get that? what is the greatest common factor between 14 and 21? 7. right? 21-14=7. take the number 7 for example, if 98 and 100 are two digits away then they couldn't both be divisible by 7
Take out 2 and get 7/28, take out 7 and get 1/4
