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 https://matthewdscott.com

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
