Understanding the Concept of Fractions and Division

What is a Fraction?

A fraction represents a part of a whole. It is expressed as two numbers separated by a slash, such as a/b, where:

• a is the numerator (the part)
• b is the denominator (the whole)
For example, in the fraction 1/16, the numerator is 1, and the denominator is 16, meaning one part out of sixteen equal parts.

Division as Repeated Subtraction or Partitioning

Division is the process of determining how many times one number (the divisor) fits into another (the dividend). When dividing 26.5 by 16, we are asking: "How many times does 16 go into 26.5?" or "What is 26.5 divided by 16?"

Calculating 1/16th of 26.5

Step-by-Step Calculation

To find 1/16th of 26.5, we perform the division: 1. Convert the problem into a multiplication: \[ \frac{1}{16} \times 26.5 \] 2. Alternatively, divide 26.5 by 16: \[ 26.5 ÷ 16 \] Let's proceed with the division method:
• Divide 26.5 by 16:
• 16 goes into 26.5 how many times?
• 16 × 1 = 16 (less than 26.5)
• 16 × 2 = 32 (greater than 26.5)
• So, 16 fits into 26.5 once, with some remainder.
• Calculate the exact quotient:
\[ 26.5 ÷ 16 = \text{?} \]
• To compute precisely, convert 26.5 into a decimal:
\[ 26.5 \]
• Perform the division:
\[ 26.5 ÷ 16 = 1.65625 \] Therefore, 1/16th of 26.5 equals 1.65625.

Alternative Calculation Using Fractions

Express 26.5 as a fraction: \[ 26.5 = \frac{53}{2} \] Then, \[ \frac{1}{16} \times \frac{53}{2} = \frac{53}{2} \times \frac{1}{16} = \frac{53}{2 \times 16} = \frac{53}{32} \] Converting to decimal: \[ \frac{53}{32} \approx 1.65625 \] This confirms our previous result.

Applications and Significance of the Calculation
