Reduce the fraction w2 plus 5w plus 6 over w2-w-12?
Ah, math time, my favorite! To reduce the fraction w^2 + 5w + 6 over w^2 - w - 12, first factor both the numerator and the denominator. The numerator factors into (w + 2)(w + 3), and the denominator factors into (w + 3)(w - 4). Cancel out the common factor of (w + 3) in both the numerator and the denominator, leaving you with (w + 2) over (w - 4). Voilà!

What is the answer for 3 over 8 divided by 1 over 4?
you switch the reciprocal around, which is always the second number,4/1,and cross cancel them to simplest form ,which is then 3/2 and 1/1, and you multiply the numerator and denominator and you will get 3/2 , so change the improper fraction and you will get your answer , 1 and 1/2.

When can you simplify a fraction or a rational algebraic expression?
When the denominator is a factor of the numerator. If there is 2x in the numerator and denominator these terms cancel.
When are you able to cross cancel a fraction?
When the numerator and denominator are not co-prime.
How do you cancel down a fraction to its lowest terms?
Find the GCF of the numerator and the denominator and divide them both by it. If the GCF is 1, the fraction is in its simplest form.
How do you convert height to inches?
Multiply it by a fraction that has a certain number of inches in the numerator and the same length as the numerator but in the units of the given height in the denominator. The original units cancel out, and you're left with inches. If the numerator and denominator of a fraction are equal, the fraction is equal to 1, and multiplying something by 1 does not change its value.
Why do the fours in the numerator and denominator cancel out?
They are a common factor and any common factor in the numerator and denominator of a ratio can be cancelled out.
What do you do to a fraction to get it in lowest form?
You cancel every factor in common to the numerator and denominator. If you cancel the highest common factor, this takes only one step. otherwise you have to keep canceling until there is nothing to cancel.
How do you cancel units of measurements?
If one unit is in the numerator and one unit is in the denominator then they can cancel out.
How can you cancel down fractions?
By dividing the numerator and denominator by their HCF
Can you cancel a numerator from 1 term and a denominator from the other?
No, you must always do the same thing to both sides of an equation or to the numerator and the denominator
How do you know if a fraction is in simplest form?
A fraction is in its simplest form if its denominator (bottom half of the fraction) and numerator (top half of the fraction) cannot be divided by the same number to equal a fraction with whole numbers in the numerator and denominator. [When you 'cancel' a fraction out (divide it to get a smaller fraction, closer to the simplest form) you must do the same sum to the numerator AND the denominator, so you must be able to divide the numerator by the same number you divide the numerator by, as the fraction cannot contain decimals or remainders (it must be a whole number] e.g. 3/6 is NOT in its simplest form, as you can divide both numbers by 3, meaning that the simplest form would be 1/3 1/3 is in its simplest form, as although you could divide the denominator by 3, you cannot divide the numerator by 3 to equal a whole number.
How do you change 0.345 in to a fraction?
Since 0.345 = (0.345/1), you multiply the numerator and the denominator by 1000. This is to get rid of the decimal. You end up with (345/1000), and then you cancel down. They are both divisible by 5, so you divide the numerator and the denominator by 5. This gives you (69/200)
How do you convert from one unit to another in a different system?
Write the conversion as a fraction. Then multiply the numerator and denominator across, then cancel any units that are both top and bottom.
