Accepted Answer

Hello today we want to go ahead and figure out which one of the given fractions is not equivalent to 7/8. So let's go ahead and first start by checking the fraction of A. So we're comparing 7/8 with 21/24. And you want to ask yourself is there a number that you can multiply both seven and eight in order to give you 21/24? And the answer to that is yes because if you multiply seven by three and you multiply eight by three this is going to give you 21/24. So both 7/8 is equivalent to 21/24 which means that the answer is not going to be a. Now let's go ahead and check be we're comparing 7/8 with 14/16. And once again you want to ask yourself is there a number that can multiply 7/8 by two? Give me 14/16? And the answer to that is yes because if I multiply both the numerator and denominator by two that's going to give me 14/16. And that means that 7/8 is equivalent to 14/16. So the answer is not going to be be. Now let's go ahead and check see. So we're gonna be comparing 7/8 with 21. I'm sorry 20 over 34 and once again you want to ask yourself is there a number that can multiply 7/8 by to give me 20/34. And the answer to that is going to be no because in the previous portions in both A and B. If you multiply 7/8 by 2/2 you get 14/16 and if you multiply both the numerator and denominator by three you get 21/24. So that means that there's no number that you can multiply 7/8 by to give you 20/34. And with that being said 7/8 is not equivalent to 20/30 for now. Let's just go ahead and check d really quick. So for D. We're comparing 7/8 with 49/ and a number that you can multiply 7/8 by is going to be 7/7 because if you multiply 7/8 by 7/ that's going to give you 49/56 that's going to be equivalent to 2 7/8. And so that means that the answer is not going to be D. So the solution to this problem is going to be C. So I hope this video helps you understand how to find equivalent fractions. And I'll go ahead and see you all in the next video
