Calculate the product of [tex]\(\frac{4}{5}\)[/tex] and [tex]\(1 \frac{1}{6}\)[/tex].

A. [tex]\(\frac{14}{15}\)[/tex]

B. [tex]\(\frac{113}{15}\)[/tex]

C. [tex]\(\frac{27}{30}\)[/tex]

D. [tex]\(\frac{13}{6}\)[/tex]

Answer :

Sure! Let's work through the problem step-by-step to solve it.

We need to calculate [tex]\( \frac{4}{5} \times 1 \frac{1}{6} \)[/tex].

1. Convert the Mixed Number to an Improper Fraction:
A mixed number like [tex]\( 1 \frac{1}{6} \)[/tex] is made up of a whole number part and a fraction part. To convert it to an improper fraction, follow these steps:
- Multiply the whole number (1) by the denominator of the fraction (6): [tex]\( 1 \times 6 = 6 \)[/tex].
- Add the numerator of the fraction (1) to this result: [tex]\( 6 + 1 = 7 \)[/tex].
- Place this result over the original denominator to get: [tex]\( \frac{7}{6} \)[/tex].

2. Multiply the Fractions:
Now, we multiply the two fractions:
[tex]\[
\frac{4}{5} \times \frac{7}{6} = \frac{4 \times 7}{5 \times 6} = \frac{28}{30}
\][/tex]

3. Simplify the Fraction:
Simplify [tex]\( \frac{28}{30} \)[/tex] by finding the greatest common divisor (GCD) of 28 and 30, which is 2:
- Divide both numerator and denominator by 2:
[tex]\[
\frac{28 \div 2}{30 \div 2} = \frac{14}{15}
\][/tex]

Therefore, the result of [tex]\( \frac{4}{5} \times 1 \frac{1}{6} \)[/tex] is [tex]\( \frac{14}{15} \)[/tex]. This fraction is approximately equal to 0.93333 when converted to decimal form.

This decimal value closely matches one of the given choices, confirming the calculation is correct.
