 Hello and welcome to the session. In this session we will discuss the question which says that Suzanne has 4 cups of choco chips. She needs 1 and 2 by 3 cups of choco chips for cake and 1 and 3 by 4 cups of choco chips for chocolate moves. How much choco chips will be left? Now let us start with the solution of the given question. Now it is given that Suzanne has 4 cups of choco chips. She needs 1 and 2 by 3 cups of choco chips for cake and 1 and 3 by 4 cups of choco chips for chocolate moves. So let us find the total amount of choco chips needed by Suzanne. So the total amount of choco chips needed by Suzanne is equal to 1 and 2 by 3 cups of choco chips for cake plus 1 and 3 by 4 cups of choco chips for chocolate moves. Which is equal to 1 and 2 by 3 plus 1 and 3 by 4. Now let us convert these mixed fractions into improper fractions. So this is equal to 3 into 1 which is 3 plus 2 that is 5. So this will be 5 by 3 plus here it will be 7 by 4. Now these fractions are unlike fractions. So we will convert these unlike fractions to like fractions that is the fractions with same denominators. Now here the calcium of the denominators that is the least common multiple of 3 and 4 is 3 into 4 which is equal to 12. Now to convert these fractions to like fractions we will change the denominator of both these fractions to 12. Now 3 into 4 is 12 so the fraction 5 by 3 can be written as 5 into 4 upon 3 into 4 which is equal to 20 upon 12. And the second fraction that is 7 by 4 can be written as 7 into 3 upon 4 into 3 which is equal to 21 upon 12. So we have converted these unlike fractions into like fractions. Now 5 by 3 plus 7 by 4 will be equal to 20 by 12 plus 21 by 12 which is equal to now here in the denominator we will have 12 and in the numerator we will have 20 plus 21. So this fraction will be equal to 41 by 12 therefore Suzanne meets 41 by 12 cups of choco chips. Now in the question it is given that Suzanne has 4 cups of choco chips and it is asked that how much choco chips will be left. So the remaining amount is equal to total amount of choco chips minus needed amount of choco chips. Now the total amount of choco chips is 4 minus needed amount is 41 by 12. Now in fraction we can write 4 as 4 by 1 minus 41 by 12. Now here also we will convert these unlike fractions to like fractions as we have done earlier. Now here the LCM of the denominators that is the LCM of 1 and 12 is 1 into 12 which is equal to 12. So the fraction 4 upon 1 can be written as 4 into 12 upon 1 into 12 which is equal to 48 upon 12 are like fractions that is these fractions have the same denominators. So now 4 upon 1 minus 41 upon 12 will be equal to 48 upon 12 minus 41 upon 12. Further this is equal to now in the denominator we will have 12 and in the numerator we will have 48 minus 41 which is equal to 7 by 12. Therefore 7 by 12 cups of choco chips are left. This is the solution of the given question and that's all for this session. Hope you all have enjoyed this session.
