To determine the decimal value of 3/8, it’s essential to perform the division of the numerator by the denominator. Dividing 3 by 8 asks how many times 8 can fit into 3. Since 8 cannot fit into 3, we proceed by considering decimal places.

By adding a decimal point to the 3 and subsequently a zero (making it 3.0), we can think of it as 30 tenths. Now, we can see how many times 8 goes into 30. It fits 3 times, which gives us 24 when multiplied (3 × 8 = 24), and subtracting that from 30 leaves us with 6. Bringing down another zero makes it 60. Now, 8 fits into 60 seven times, giving us 56. Subtracting yields 4, and bringing down another zero gives us 40. The number 8 fits into 40 exactly 5 times, leading to the result of 0.375.

Hence, the decimal form of 3/8 is 0.375, which corresponds to the correct answer. This method clearly illustrates the process of converting a fraction to a decimal.
