In the given question we are told that mrs.
00:03
Perez bought half a kilogram of chicken, half kilogram of chicken, one by two kilogram of chicken and three by four kilogram of beef.
00:19
And now we are asked how many meat did she buy in total? so in order to find the total amount of meat she has bought, total amount of meat she has bought, we can add 1 by 2 and 3 by 4.
00:42
So the process that we have we are following to find the answer is addition of these two fractions.
00:49
And now how do we perform addition between two fractions 1 by 2 and 3 by 4? so first what we would do is we would make the denominators of each of these fractions the same.
01:01
So how do we do this? we can take the fraction 1 by 2 and we can see that when we multiply the numerator and the denominator with 2, the fraction changes to 2 by 4.
01:13
So the value of the fraction has not changed but the numerator and the denominator has changed.
01:19
So now instead of 1 by 2 we can write 2 by 4 over here and then the 1.
01:25
Addition would be 2 by 4 plus 3 by 4 and when 2 fractions have the same denominators and we are adding them we can combine them and write it as 2 plus 3 divided by since they have the same denominator we will have the denominator we will have a common denominator which is 4 so 2 plus 3 is equal to 5 so 5 by 4 kilogram of meat is what she has bought 5 by 4 kilogram of meat.
01:57
So this is the required answer.
02:01
Now in the question we have a few options and we can see that the first question that is the process that we will use is addition which is option a in the question number 15 and in the second question we cannot see 5 by 4 as an answer...
