Answer 1

13/6000-17/14400=71/72000
19/3960+23/132=709/3960

Answer 2

13/6000=0,002
17/14400 = 0,001
0,002-0,001 = 0,001

Answer 3

13/6000 - 17/14400 =

To perform subtraction of fractions, we need a common denominator. The smallest common multiple of 6000 and 14400 is 14400. So, we need to convert the fractions to have a denominator of 14400.

13/6000 = (13/6000) * (24/24) = 312/14400 17/14400 = (17/14400) * (10/10) = 170/14400

Now, we can perform the subtraction:

13/6000 - 17/14400 = 312/14400 - 170/14400 = 142/14400 = 71/7200

Therefore, 13/6000 - 17/14400 = 71/7200.

19/3960 + 23/132 =

To perform addition of fractions, we need a common denominator. The smallest common multiple of 3960 and 132 is 7920. So, we need to convert the fractions to have a denominator of 7920.

19/3960 = (19/3960) * (2/2) = 38/7920 23/132 = (23/132) * (60/60) = 1380/7920

Now, we can perform the addition:

19/3960 + 23/132 = 38/7920 + 1380/7920 = 1418/7920

We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 178:

1418/7920 = (1418/178) / (7920/178) = 8/45

Therefore, 19/3960 + 23/132 = 8/45.
