3/4 + 5/6 = 9/12 + 10/12 = 19/12 or 1 and 7/12
Write 12, followed by 9 zeroes. Or 12 zeroes, depending where you live - but 9 zeroes is more common.
5/9 − 5/12 = 5/36

12/5 ÷ 12/9 = 12/5 x 9/12 = 9/5 = 14/5
9 over 12 is also 3/4 or 18/24 or 27/36 or 36/48 or 45/60

- 5m + 12 = - 9 subtract 12 from each side - 5m + 12 - 12 = - 9 - 12 - 5m = - 21 divide both sides integers by - 5 (- 5/- 5)m = - 21/- 5 m = 21/5 -----------------------check in original equation = 5(21/5) + 12 = - 9 - 105/5 + 12 = = 9 (now, 12 = 60/5 , so) - 105/5 + 60/5 = - 9 - 45/5 = - 9 - 9 = - 9 ----------------checks
3/4 + 5/6 = 9/12 + 10/12 = 19/12 or 1 and 7/12
5+7+9+12+12 = 45 and 45/5 = 9 which is the mean average
5/12 - 9/12 = -4/12
5/9 − 5/12 = 5/36
Write 12, followed by 9 zeroes. Or 12 zeroes, depending where you live - but 9 zeroes is more common.
