Knowing the LCM of the denominators of unlike fractions will help you find the least common denominator, a necessary step in adding and subtracting them.
Knowing the GCF of a numerator and denominator will tell you if the fraction can be reduced.
Knowing the LCM will help when adding or subtracting unlike fractions. By finding the LCM of the denominators, (called the lowest common denominator) you can convert unlike to like fractions and proceed with the adding or subtracting. Knowing the GCF helps reduce a fraction. By finding the GCF of the numerator and the denominator and dividing both of them by it, you can reduce a fraction to its lowest terms (simplest form). If the GCF is 1, the fraction is in its simplest form. You can successfully multiply fractions without knowing the GCF or LCM.
0.238095238 as a fraction is 10/42. To convert the decimal to a fraction, you can multiply both the numerator and denominator by 10, which gives you 2.38095238/10. Simplifying this fraction by dividing both the numerator and denominator by 0.238095238 gives you 10/42.
0.787 as a fraction is 787/1000
Finding an LCM will help when you want to add and subtract fractions.
.016 in fraction form is 2/125! Hope I could help!

It will help you in life a ton! knowing how to add,multiply,subtract,and a lot of other math stuff will help you get good grads, get a good job, and help you know if your getting ripped off at a yard sale.
In order to add or subtract fractions, the denominator (bottom number) has to be the same. In order to make it the same, you find the LCM and multiply the fraction by whatever is necessary to make the denominator the LCM. FOR EXAMPLE: 1/3 + 2/5 The LCM of 3 and 5 is 15. To make the 3 in 1/3 15, you multiply the whole fraction by 5 over 5 (it simplifies to 1 so you aren't really changing the fraction by multiplying it by 1). 1/3 * 5/5 is 5/15 You multiply 2/5 times 3 over 3 using the same principle 2/5 * 3/3 is 6/15 NOW you can add 5/15 and 6/15 to get 11/15.
Knowing factors will help you find a GCF. To simplify a fraction, divide the numerator and the denominator by their GCF.
Knowing the least common multiple of the denominators will help you find a common denominator when adding and subtracting unlike fractions. Knowing the greatest common factor of the numerator and the denominator will help you reduce the fraction if possible.
The abbucus helps people who can't use modern technology to count (add, subtract, multiply and divide).
it helps because you add subtract multiply divide and other mathematical operationsyou SOLVE so you can get the answers
It is just a little nice reminder of the trick that will help you remember steps. it stands for Parenthesis, exponents, multiply, divide, add, subtract!

Change each fraction to an equivalent fraction with the same denominator. 3/8+5/12= 9/24+10/24=19/24
i need help finding the answer ummm can some one help me like how to do 3(y+6)=30 multiply it out... 3y + 18 = 30 3y = 12 y = 4
