Answer 3

To solve the expression $\frac{2}{5} \times 4 \frac{1}{9} - 1 \frac{1}{8} \times 4 \frac{1}{9}$, let's break it down step by step:

1. Convert the mixed numbers to improper fractions.
2. Perform the multiplications and subtractions.

Starting with the first term:

$\frac{2}{5} \times 4 \frac{1}{9}$

Convert the mixed number to an improper fraction:

$4 \frac{1}{9} = \frac{37}{9}$

Now multiply:

$\frac{2}{5} \times \frac{37}{9}$

Multiply the numerators and denominators separately:

$\text{Numerator: } 2 \times 37 = 74$ $\text{Denominator: } 5 \times 9 = 45$

So, the result is $\frac{74}{45}$.

Moving on to the second term:

$1 \frac{1}{8} \times 4 \frac{1}{9}$

Convert the mixed number to an improper fraction:

$4 \frac{1}{9} = \frac{37}{9}$

Now multiply:

$1 \frac{1}{8} \times \frac{37}{9}$

Multiply the numerators and denominators separately:

$\text{Numerator: } 8 \times 1 + 1 = 9$ $\text{Denominator: } 8 \times 9 = 72$

So, the result is $\frac{9}{72}$.

Now, subtract the two results:

$\frac{74}{45} - \frac{9}{72}$

To subtract, find a common denominator, which is 72 in this case:

$\frac{74}{45} - \frac{9}{72} = \frac{74 \times 8}{45 \times 8} - \frac{9}{72}$

$= \frac{592}{360} - \frac{9}{72}$

Now, subtract the numerators:

$\frac{592 - 9}{360} = \frac{583}{360}$

The result is $\frac{583}{360}$.
