No you do not HAVE TO. But you are well advised to do so. You are far more likely to run into problems or make mistakes if you try to go through the multiplication process using mixed fractions.
WE just have to check if the numerator is greater than the denominator. Eg: 8/3 is an improper fraction. Every mixed fraction is an improper fraction.
Not every fraction can be written as an improper one. Every improper fraction is greater than ' 1 '. Sadly, 2/5 is less than ' 1 ', so there's nothing you can do to it that can magically turn it into an improper one.
Certainly. Every fraction is a ratio.
Yes, it can. In fact every mixed number has an equivalent improper fraction.
No. Every proper fraction is less than 1, but improper fraction will be greater than 1.
Any whole number, n, can be written as the fraction n/1.Multiplication of a fraction, p/q by a whole number n is the same as multiplying p/q by n/1.Furthermore, the process of multiplying proper fractions and improper fractions is the same and that gives the equality of the two processes.
The percent sign in every percent means, "out of 100." Therefore, to express a percent as a fraction, simply place the percent number over 100 and simplify if possible. If it is an improper fraction, to change it into a mixed number, see: http://wiki.answers.com/Q/How_do_you_express_a_fraction_into_a_mixed_number&updated=1&waNoAnsSet=2
"percent" means for every hundred, or alternatively, out of 100. Finding some percentage of a number is multiplying that number by the fraction of the percentage over 100. eg to find 53% of a number, multiply by the fraction 53/100
There is NO fraction that is equal to EVERY fraction.
It's called an improper fraction.
Every unit fraction is in its simplest form. Every unit fraction is a proper fraction.
Every fraction has infinitely many fractions that areequivalent to it. So every fraction is equivalent.Every fraction has infinitely many fractions that areequivalent to it. So every fraction is equivalent.Every fraction has infinitely many fractions that areequivalent to it. So every fraction is equivalent.Every fraction has infinitely many fractions that areequivalent to it. So every fraction is equivalent.
