1/8 Inch vs. 0.15 Inch: What's the Difference?

Introduction:

In the world of measurements, fractions and decimals are often used to represent the same value. But are they always equal? In this article, we'll delve into the fascinating world of fractions and decimals to determine if 1/8 inch is indeed the same as 0.15 inch.

Fractions vs. Decimals:

• A fraction represents a part of a whole, written in the form of a/b, where a is the numerator and b is the denominator.
• A decimal represents a number in base 10, written without a denominator.

Converting Fractions to Decimals:

To convert a fraction to a decimal, simply divide the numerator by the denominator. For example, 1/8 ÷ 8 = 0.125.

1/8 Inch in Decimals:

1/8 inch can be converted to a decimal using the fraction-to-decimal conversion method:
1/8 ÷ 8 = 0.125

0.15 Inch in Fractions:

0.15 inch can be converted to a fraction by dividing it by 100, which is equivalent to multiplying it by 1/100:
0.15 × 1/100 = 15/100

Simplifying the fraction:

15/100 can be simplified by dividing both the numerator and denominator by 5, resulting in:
15÷5/100÷5 = 3/20

Conclusion:

We have determined that 1/8 inch is not the same as 0.15 inch. While they both represent 0.125 in decimal form, their fractional representations are different. 1/8 inch is equivalent to 3/20 inch in fraction form, while 0.15 inch is equivalent to 15/100 inch.
