1 answer

To solve the expression 415+13, we start by finding a common denominator. The least common multiple (LCM) of 15 and 3 is 15.

Now we'll rewrite 13 with a denominator of 15:

13=1×53×5=515

Now we can add the two fractions:

415+515=4+515=915

Next, we can simplify 915 by dividing both the numerator and the denominator by their greatest common divisor, which is 3:

9÷315÷3=35

Thus, the final result of 415+13 is 35.

If you meant to compare this result to options A through D, it is clear that:

  • A: 518
  • B: 53
  • C: 45
  • D: 35

The correct answer is D: 35.
