what is the easiest way to add improper fractions? i promise i won’t suggest anything improperwhen talking about adding fractions. though the definition is derivative. and a simple answer is integral to my abilityto explain this concept to my kids. and for goodness sake, don’t tell me the joke abouthow with log tables, even adders can multiply.
How To Add Top Heavy Fractions, the logarithm jokes fell out of favor whenlog tables and slide rules became obsolete. though the simplest way to add them is witha scientific calculator. kids still have to show their work on mathhomework. improper fractions are the most likely wayto successfully subtract a mixed fraction,
one with a number and a fraction of one. youstart by multiplying the denominator with the whole number. isn’t that the divisor? same difference. the product of the divisortimes the whole number is added to the numerator or top number. and that is the improper fraction. and you have to do the same thing to the othernumber to be subtracted. once both fractions are improper, you can subtract the top numberswhile keeping the bottom number the same. then it becomes a simple math problem andyou’re done.
only if the answer can be an improper fractionor you have a number on top smaller than the bottom number. otherwise, you have to convertthe answer to proper format. so an improper fraction isn’t the rightanswer if you have to simplify it. the teacher will accept 2 and 3/4, but not11/4, which has to be turned into 2.75 in most cases. what if the numbers have a different divisor? then you have to convert the fractions intothe same divisor. that is easy when 3/8 becomes 6/16 to add to 7/16, but a lot harder with56 or 84. the end result that matters to me is a goodgrade in math class.
