Five and three fourths plus three and five twelves? - Answers

Make it simpler to use.5 and 3/4ths plus3 and 5/12thsThree fourths and five twelveths need to have a common denominator. Since 4 goes into 12 three times you need to change the first fraction to 12ths. 3 times 3 is 9 and 3 times 4 is 12. So 9/12ths is the same as 3/4ths.Now you can add them. Do the whole numbers first. 5 plus 3 equals 8.Then do the fractions. Add the top numbers together, 9 plus 5 and leave the 12 alone. This gives you 14/12ths. Since the top number is greater than the bottom number, we know that the number is greater than 1 and must be reduced. 12/12 is the same as one whole and that would leave two left over. This would give us 1 and 2/12ths or reduced further 1 and 1/68 plus 1 1/6 equals 9 1/6th.The answer is nine and one sixth.
