Answer:

31/40

Step-by-step explanation:

Given expression:

\dfrac{2}{5} + \dfrac{3}{8}

Note: Both fractions must have same denominators if we want to perform addition, subtraction, multiplication, or division.

The only way to simplify this expression is to have a common denominator, which can be determined by the LCM of 5 and 8.

  • ⇒ Multiples of 5: 5, 10, 15, 20, 25, 30, 35, 40, 45...
  • ⇒ Multiples of 8: 8, 16, 24, 32, 40, 48, 56, 64, 72...

Multiply the denominators with such a number that is equivalent to 40.

Note: The number you are multiplying should also be multiplied to the numerator.

\rightarrow \dfrac{2 \times 8}{5 \times 8} + \dfrac{3 \times 5}{8 \times 5}

\rightarrow \dfrac{16}{40} + \dfrac{15}{40}

Finally, simplify the expression to determine the solution.

\rightarrow \dfrac{31}{40}

Since 31 is a prime number, we can't simplify this fraction. Thus, the final answer is 31/40.
