WebWhy some people say it's true: It works when we add numerators like \dfrac b a + \dfrac c a = \dfrac {b+c} a ab + ac = ab+ c, so it's the same for denominators.

WebIf we had a simpler problem such as 3 + blank = 8, we would do 8-3 = 5. Similarly, for 2/5 + blank = 7/10, we would do 7/10 - 2/5. We can use 10 as a common denominator because 5 divides evenly into 10. Multiplying top and bottom of 2/5 each by 2 gives 4/10, so 2/5 = 4/10. So the blank is 7/10 - 2/5 = 7/10 - 4/10 = 3/10. The answer is 3/10. WebAn explanation why we cannot just add denominators when adding fractions education sales pitch

WebWhenever you multiply the denominator by something (in this case, 4) you also have to multiply the numerator. In this case, 5/6 would equal 20/24, which is equivalent. You do the same thing for 6/8: It becomes (6*3)/24, which equals 18/24. P.S. To check this, you can always simplify your new fraction to make sure it is still equivalent. Web20/24 + 18/24 = 38/24. This is an improper fraction. So now, you have to convert it to a mixed number. 24 goes into 38 one time with 14 left over. So we get: 1 14/24, or simplified, 1 7/12. Now we add the whole numbers: 5 + 5 = 10. Then, we add the mixed number to 10 which makes 11 7/12. Your final answer is 11 7/12. education sales and marketing
