1 2/5 divided by 21
Which example is correct
7/5 * 1/21 = 7/105 = 1/15
or is it?
5/7 * 21/1 = 105/7 =15
You asked this question yesterday. The answer is still the same.
To solve the division problem 1 2/5 divided by 21, we can convert the mixed number 1 2/5 into an improper fraction.
1 2/5 = (5*1 + 2)/5 = 7/5
Now, we have 7/5 divided by 21. To divide fractions, we can multiply the first fraction by the reciprocal of the second fraction. In this case, we need to multiply 7/5 by 1/21.
So, let's calculate:
7/5 * 1/21 = (7*1)/(5*21) = 7/105
Therefore, the result is 7/105.
Now, let's compare the example you provided:
1. 7/5 * 1/21 = 7/105 = 1/15
2. 5/7 * 21/1 = 105/7 = 15
Example 1 is correct. The result of 7/5 divided by 21 is 7/105, which is indeed equal to 1/15.
If you have asked the same question before and received the same response, it means that the answer remains consistent.
