Answer:

5/8

Step-by-step explanation:

1 + 3/8 - 3/4 =

1 + (1 × 3)/(1 × 8) - (2 × 3)/(2 × 4) =

1 + 3/8 - 6/8 =

1 + (3 - 6)/8 =

1 - 3/8

- 3/8 already reduced to the lowest terms.

The numerator and the denominator have no common prime factors.

Their prime factorization:

3 is a prime number;

8 = 23

1 - 3/8 =

(1 × 8)/8 - 3/8 =

(1 × 8 - 3)/8 =

5/8
