What number can be divided by 15, 5, and 3?

The answer is 30

13/15 + 2/3 - 3/5 = 13/15 + 10/15 - 9/15 = 14/15

To add the fractions 3/10 and 7/12, you need to find a common denominator. The common denominator is the least common multiple (LCM) of the two denominators, which in this case is 60.

To find the sum of the fractions, you should convert each fraction to an equivalent fraction with the common denominator of 60.

First, consider 3/10. To convert it to a fraction with a denominator of 60, you need to multiply both the numerator and denominator by 6. This gives you (3 * 6) / (10 * 6) = 18/60.

Next, consider 7/12. To convert it to a fraction with a denominator of 60, you need to multiply both the numerator and denominator by 5. This gives you (7 * 5) / (12 * 5) = 35/60.

Now that both fractions have the same denominator of 60, you can add them together. The sum is (18/60) + (35/60) = 53/60.

Therefore, 3/10 + 7/12 = 53/60.
