There is actually no specific formula to subtract fractions but rather a method to accomplish this. First you have to obtain a common denominatior between the two fractions in order to subtract. This is easiest when you just multiply the denominators.

If you have 1/4 and 1/9 you multiply the denominator to have a common one. This would give us 36. then you would have to multiply the numerators by the number you multiplied the denominator.

This means that 1/4 would become 9/36 because you multiplied the bottom by 9 in order to get 36. You can check to see if you did this right by simplifying the fraction and seeing if you got your original fraction. Once you have these new common fractions you simply subtract the numerators and put them over the common denominator.

9/36 - 4/36 = 5/36 which cannot be simplified

For adding or substracting fractions first of all we should calculate the LCM( Lowest Common Multiplier) of the denominators in both of the fractions.

The Subscripts in a Chemical formula explain how the atoms in that compound are chemically bonded. As a fraction of an atom cannot bond, the subscripts cannot be fractions. Coefficients, however which go before a chemical formula in chemical equations may be fractions. This is because they explain the ratio of the number of moles of each species required for the reaction and it is possible to have a fraction of a mole of something.

Not in Excel. Excel does not use fractions. If you need to use fractions, then turn them into decimals. You can represent 1/2 in excel with the formula =1/2.

If you mean someone is resting then it's "descanso". If you mean someone is substracting then it's "restando".

The answer would be -7 4/5. First convert the mixed numbers into fractions. Then use the algebraic formula for addition of fractions: a/b + c/d = (ad + bc) / bd. Last, reduce the fractions.

There is no formula for dividing fractions, but there is a way of doing it. When you a fraction divided by another fraction like below... 1/2 divided by 4/7.... Swap the second fraction around and then multiply like this... 1/2 multiplied by 7/4.... And when multiplying fractions, multiply the numerators (top number) together, and the denominators (bottom number) together (1x7)/(2x4) = 7/8 Simple

if substracting by two negatives your going to add ex: -2-(-5) it would be positive 7. if your substracting with two differ numbers it you would substract and take the sign the sign of the biggest number.ex: 2+(-3) it would be-1 sice 3 is bigger than2 you take the sign of 3

The formula for the area of a triangle is A= o.5 x h x w, or if you like to use fractions, A= 1/2 x h x w.

As a review, similar fractions (also like fractions) are fractions having the same denominators

adding and subtracting protons from a gold atom would no longer make it gold.

like fractions,unlike fractions proper fractions ,improperfractions equivalent fractions

Like fractions are the fractions which have the same denominator and unlike fractions are the fractions which do not have the same denominator.

Firstly, we have to make the two decimal numbers as like terms. That is, 476.234 and 538.400 Now, Substracting 476.234 from 538.400 we get 538.400 - 476.234 = 62.166

9 x 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 100

A base anhydride is derived by substracting a water molecule from the base molecule (as same as in acid anhydrides). As an example, the base anhydride of ammonium hydroxide is ammonia.

There are three types of fractions that are used in mathematics. The three types of fractions are, mixed fractions, proper fractions, and improper fractions.

Regular fractions are the fractions with a numerator that is less than the denominator and irregular fractions are fractions with a denominator less than the numerator.

You basically have to learn separately how to do different things with fractions, including finding a common denominator; converting fractions to a different denominator; simplifying fractions; adding and subtracting fractions; multiplying fractions; dividing fractions.

Two methods: (1) Convert the mixed fractions to improper fractions first. This is generally the easier method. (2) Use the distributive property. For example, 2 x 3 1/3 = 2 x (3 + 1/3) = 2 x 3 + 2 x 1/3 = 6 + 2/3 = 6 2/3.

n / d = q n = numerator d = denominator q = quotient (or answer) It's probably better to think of a fraction as a form rather than a formula.
