Understanding 1/2 of 2 1/4 tsp: A Comprehensive Guide

Whether you're baking a cake or preparing a recipe that requires precise measurements, understanding how to calculate half of a mixed fraction like 2 1/4 teaspoons (tsp) can be quite useful. This guide will walk you through the process step-by-step, ensuring you get the correct amount every time.

Solving the Problem

The problem at hand is to find (frac{1}{2}) of (2 frac{1}{4}) tsp. We will break this down into a few simple steps.

Step 1: Convert the Mixed Fraction to an Improper Fraction

First, we need to convert the mixed number (2 frac{1}{4}) to an improper fraction. To do this, we multiply the whole number (2) with the denominator (4) and then add the numerator (1).

[2 frac{1}{4} 2 times 4 1 8 1 9,] so it becomes (frac{9}{4}) tsp.

Step 2: Calculate Half of the Improper Fraction

Next, we need to find (frac{1}{2}) of (frac{9}{4}). This involves multiplying the two fractions.

[frac{1}{2} times frac{9}{4} frac{1 times 9}{2 times 4} frac{9}{8}.]

Step 3: Convert the Result Back to a Mixed Number

The result of (frac{9}{8}) is still an improper fraction. To express this in a more understandable form, we convert it back to a mixed number.

[frac{9}{8} 1 frac{1}{8}.]

So, (frac{1}{2}) of (2 frac{1}{4}) tsp is (1 frac{1}{8}) tsp.

Another Approach

To verify the answer, another method is to break the problem into parts. First, find half of 2 (which is 1) and half of 1/4 (which is 1/8). Adding these results gives us (1 frac{1}{8}) tsp, or (1 frac{1}{8}) tsp.

Conclusion

Whether you use the improper fraction method or the parts addition method, the result is the same. This guide has demonstrated both approaches to help you accurately measure (1 frac{1}{8}) tsp. Perfect for any baking or cooking task that requires precision.
