Answer 2

Let's solve each of these multiplication problems involving fractions:

1. $2 \frac{4}{25} \times 5$:

   To multiply a whole number by a mixed number, you can first convert the whole number to a fraction with the same denominator as the mixed number.

   $2 = \frac{2}{1}$

   Now, multiply the numerators and denominators separately:

   $\frac{2}{1} \times \frac{4}{25} \times 5 = \frac{2 \times 4 \times 5}{1 \times 25}$

   $= \frac{40}{25}$

   Simplify the fraction:

   $= \frac{8}{5}$

   So, $2 \frac{4}{25} \times 5 = 8/5$.

2. $3 \frac{3}{5} \times \frac{7}{18}$:

   Follow the same process:

   $3 = \frac{3}{1}$

   $\frac{3}{1} \times \frac{3}{5} \times \frac{7}{18} = \frac{3 \times 3 \times 7}{1 \times 5 \times 18}$

   $= \frac{63}{90}$

   Simplify the fraction:

   $= \frac{7}{10}$

   So, $3 \frac{3}{5} \times \frac{7}{18} = 7/10$.

3. $5 \frac{1}{2} \times 3 \frac{3}{11}$:

   $5 \frac{1}{2} = \frac{11}{2}$ and $3 \frac{3}{11} = \frac{36}{11}$

   $\frac{11}{2} \times \frac{36}{11} = \frac{11 \times 36}{2 \times 11}$

   Cancel out common factors:

   $= \frac{36}{2}$

   $= 18$

   So, $5 \frac{1}{2} \times 3 \frac{3}{11} = 18$.
