What does two eighths plus three sixths equal?
2/8 + 3/6 First, you have to make the denominators equal(the number on the bottom, so in this case the 8 and the 6). This is called finding the LEAST COMMON DENOMINATOR. 8 and 6 both go into 24 with no remainder To get the denominators to be 24, you have to multiply 8 by 3 and 6 by 4. Now, since you multiplied the denominators by a number, you have to multiply the numerator with that same number. 2 * 3 = 6 and 8 * 3 = 24 3 * 4 = 12 and 6 * 4 = 24 12/24 + 6/24 Now you can add the fractions together! Since the denominators are equal, add the numerators together. 6 + 12 = 18 The denominator remains the same so the answer is: 18/24
How do you multiply fractions when the denominators are both the same?
As normal: numerator x numerator over denominator x denominator: eg 4/9 x 6/9 = 24/81 which can be simplified to 8/27
What is 7 over 8 minus 2 over 3?
5 over 24. [If you do not understand how to get that answer, here is how. To subtract fractions you must find the common denominator. In this problem you must find the common denominator between 8 and 3. They both can multiply into 24 so that is your common denominator. Now 8 times 3 will give you the denominator of 24, but you must also multiply the 7 by 3 to make the fraction the same. The first fraction will be 21/24. The next fraction will be 16/24 because 2 times 8 is 16 and 3 times 8 is 24. Now all that you have to do is subtract the numerators. 21 - 16 = 5 so your answer is 5/24.]
How Do You Make Fractions Have The Same Denominators?
You need to find the lowest common denominator. For example- 1/6 + 2/12 = 2/12 + 2/12=4/12 you need to multiply the 6 two times to get 12 and what you do to the bottom you always do to the top so you multiply 1 by 2 and get 2!
How do you subtract and simplify 5 over 18 minus 7 over 24?
In order to subtract, the denominators must be the same. The easiest way is to multiply 18 and 24, which equals 432. You will also have to multiply the numerators. Think of it like this: 24*(5/18) and 28*(7/24). You are multiplying the fraction as a whole. So, 24*5=120 and 18*7=126 Now the fractions are 120/432 and 126/432. Subtract them, and you get -6/432. To simplify, find a common number that both the numerator and denominator can divide by. Let's try 6. -6/6 = -1, and 432/6 = 72. Your simplified fraction is -1/72.
