 Hello and welcome to the session. In this session we discussed the following question which says compare the ratios 2 is to 3 and 5 is to 7. When we have to compare two given ratios then first we will express each of the given ratios in the form of a fraction in the simplest form. And then we will make the denominators of both the fractions equal so that we can compare both these fractions. So let's try to compare the two given ratios. The given ratios are 2 is to 3 and 5 is to 7. So we can write 2 is to 3 as 2 upon 3 and 5 is to 7 as 5 upon 7. Now let's find out the LCM of the denominators of both these fractions which are 3 and 7. So LCM of 3 and 7 is equal to 21. Now we will make the denominators of each of these fractions as 21. So first let's consider 2 upon 3. To make its denominator 21 we will multiply the numerator and denominator by 7. So this is equal to 14 upon 21. Then consider the other fraction which is 5 upon 7. To make its denominator equal to 21 we will multiply its numerator and denominator by 3. And this is equal to 15 upon 21. So we have now got 2 upon 3 is written as 14 upon 21 and 5 upon 7 is written as 15 upon 21. Now you can easily see that 15 upon 21 is obviously greater than 14 upon 21 which means that 5 upon 7 is greater than 2 upon 3 or you can say that the ratio 5 is to 7 is greater than the ratio 2 is to 3. So this is how we compare the two given ratios. This completes this session. Hope you have understood the solution of this question.
