Understanding the Problem

In this problem, we are required to multiply two mixed numbers and fractions, 4124 \frac{1}{2} and 34\frac{3}{4}. To solve this problem, we need to first convert the mixed number 4124 \frac{1}{2} into an improper fraction.

Converting Mixed Numbers to Improper Fractions

A mixed number is a combination of a whole number and a fraction. To convert a mixed number to an improper fraction, we multiply the whole number by the denominator and then add the numerator. The result is then written as the new numerator over the denominator.

In this case, 4124 \frac{1}{2} can be converted to an improper fraction as follows:

412=(4×2)+12=8+12=924 \frac{1}{2} = \frac{(4 \times 2) + 1}{2} = \frac{8 + 1}{2} = \frac{9}{2}

Multiplying the Fractions

Now that we have converted the mixed number to an improper fraction, we can multiply the two fractions together.

92×34=9×32×4=278\frac{9}{2} \times \frac{3}{4} = \frac{9 \times 3}{2 \times 4} = \frac{27}{8}

Simplifying the Result

The result of the multiplication is 278\frac{27}{8}. However, we can simplify this fraction by dividing both the numerator and the denominator by their greatest common divisor (GCD).

The GCD of 27 and 8 is 1, so the fraction 278\frac{27}{8} is already in its simplest form.

Conclusion

In conclusion, the product of 4124 \frac{1}{2} and 34\frac{3}{4} is 278\frac{27}{8}.

Why is this Important?
