Answer 3

To solve the expression 19/2 - 7/25, we need to find a common denominator for the fractions and then subtract them.

Finding a common denominator:

The denominators of the fractions are 2 and 25. To find a common denominator, we need to find the least common multiple (LCM) of 2 and 25. The LCM of 2 and 25 is 50.

Converting the fractions:

To convert the fractions to have a common denominator of 50, we need to multiply the numerator and denominator of each fraction by the same value that will result in a denominator of 50.

For the fraction 19/2: - Multiply the numerator (19) by 25: 19 * 25 = 475 - Multiply the denominator (2) by 25: 2 * 25 = 50

So, 19/2 is equivalent to 475/50.

For the fraction 7/25: - Multiply the numerator (7) by 2: 7 * 2 = 14 - Multiply the denominator (25) by 2: 25 * 2 = 50

So, 7/25 is equivalent to 14/50.

Subtracting the fractions:

Now that both fractions have a common denominator of 50, we can subtract them.

475/50 - 14/50 = (475 - 14)/50 = 461/50

Therefore, the result of the expression 19/2 - 7/25 is 461/50.
