It does not matter what they are as long as both are the same. 1 = 2/2 = 17/17 = 958/958 and so on.
Multiply the numerator of the fraction by the same amount that you multiply the denominator of that fraction.
When the numerator and denominator of the division do not have a common factor.
when you are writing a division problem as a fraction u take the remainder of your problem and make it the numerator and make the number you are dividing by the denominator
The top number in a fraction is called the "numerator". The bottom number is called the "denominator"
When the numerator and denominator are relatively prime.
When dividing by a fraction, the second fraction (the divisor) is changed into its reciprocal by swapping the numerator and denominator over (turning it upside down) and then it is multiplied by the first number (fraction).
The numerator is the top number in any fraction.
To calculate this sort of subtraction problem the two fractions have to be converted so that they share the same denominator - the number below the line. This is done by calculating the lowest common denominator they share. As 11 is a prime and 63 is not a multiple of it, then the lowest common denominator will be 63 x 11 = 693. * To convert the 46/63 to a fraction with 693 as its denominator we need to multiply both the numerator and the denominator by 11. This gives 506/693. * To convert the 3/11 to a fraction with 693 as its denominator we need to multiply both the numerator and the denominator by 63. This gives 189/693. Now we can subtract 189 from 506. That gives 317. * 317/693 As 317 is a prime, and 693 is not a multiple of it, that fraction can not be simplified.
by working it out
Given two fractions, you find the Least Common Denominator by finding the Least Common Multiple of the two Denominators. Then for each fraction, the new numerator the product of the is old numerator, and whatever multiplier you use to get the new denominator. Example: 1/14 - 1/21: The LCM of 14 & 21 is 42, so for the first fraction: 3 x 14 = 42, so the new numerator is 3 x 1 = 3. For the 2nd fraction: 2 x 21 = 42, so the new numerator is 2 x 1 = 2. The new subtraction problem is: 3/42 - 2/42 = 1/42
A fraction is a way of representing division of a 'whole' into 'parts'. The Numerator is the number of parts chosen, and the Denominator is the total number of parts. A fraction is a division problem, basically:½ means "one divided by two"¾ means "three divided by four"Another way of thinking of it is:½ "one of two pieces" and¾ "three of four pieces"it is 7.10
You can multiply anything by 1 without changing it, a fraction with a numerator that's equal to its denominator equals 1, and common factors between a fraction's numerator and denominator cancel out. Also, whenever you see the word per in a word problem, think division.You're converting a fraction with grams in the numerator and cubic centimeters in the denominator to one with kilograms in numerator and cubic meters in the denominator. Therefore, you want to multiply by a fraction with grams in the denominator (to cancel out the grams) and kilograms in the numerator, and you want the quantities to be equal so the fraction equals 1. You also want to multiply by a fraction with cubic centimeters in the numerator (to cancel out the cubic centimeters) and cubic meters in the numerator that equals 1....(1 g/cm2) * (kg/1000g) * (10000 cm2/m2) = 10 kg/m2Since the second and third fractions each equals 1,1 g/cm2 = 10 kg/m2
