What do you do to the numerator in a lowest common denominator problem?
Multiply the numerator of the fraction by the same amount that you multiply the denominator of that fraction.
How do you know when to turn a division problem into a fraction?
When the numerator and denominator of the division do not have a common factor.
Why can you write a division problem as a fraction?
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
What is the top number in a division problem called?
The top number in a fraction is called the "numerator". The bottom number is called the "denominator"
Fourth grade math how do you know a fraction is in simplest form my sister's homework problem?
When the numerator and denominator are relatively prime.
What do you turn the second fraction into in a dividing problem?
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).
Is the numerator the parts in all in a fraction problem?
The numerator is the top number in any fraction.
What is 46 over 63 - 3 over 11?
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.
How do you find an equivalent fraction by dividing?
For example you have 5/25. You pick a number for example 10. you multiply the denominator by 10 and that's the new denominator and you would multiply the numerator by 10 also and that would be your new numerator. So in this case it would be 50/250. Now you don't have to multiply them by 10 but you do have multiply the numerator and denominator by the same number that you pick.
How do you find the LCD when subtracting rational expressions?
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
How do you find the answer to a subtraction fraction problem?

What is a fraction?
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
