Answer 2

$4\frac{2}{7} *1\frac{3}{4}-3\frac{9}{25}/\frac{4}{5} +1\frac{1}{2} = 7\frac{1}{2} - 4\frac{1}{5} + 1\frac{1}{2}= 3\frac{3}{10}+1\frac{1}{2}=4\frac{4}{5}$

Answer 3

Let's break down the given expression step by step:

1. Convert mixed numbers to improper fractions: $4 \frac{2}{7} = \frac{4 \times 7 + 2}{7} = \frac{30}{7}$ $1 \frac{3}{4} = \frac{1 \times 4 + 3}{4} = \frac{7}{4}$ $3 \frac{9}{25} = \frac{3 \times 25 + 9}{25} = \frac{84}{25}$ $1 \frac{1}{2} = \frac{1 \times 2 + 1}{2} = \frac{3}{2}$

2. Simplify the given expression: $\frac{30}{7} \times \frac{7}{4} - \frac{84}{25} : \frac{4}{5} + \frac{3}{2}$

3. Perform the division: $\frac{84}{25} : \frac{4}{5} = \frac{84}{25} \times \frac{5}{4} = \frac{21}{5}$

4. Rewrite the expression: $\frac{30}{7} \times \frac{7}{4} - \frac{21}{5} + \frac{3}{2}$

5. Multiply the fractions and perform addition: $\frac{30 \times 1 - 21}{7} + \frac{3}{2}$ $= \frac{9}{7} + \frac{3}{2}$

6. Find a common denominator, which is 14: $= \frac{9 \times 2}{7 \times 2} + \frac{3 \times 7}{2 \times 7}$ $= \frac{18}{14} + \frac{21}{14}$

7. Add the fractions: $= \frac{18 + 21}{14}$ $= \frac{39}{14}$

Now, $\frac{39}{14}$ cannot be simplified further into a mixed number, so the final answer is $\frac{39}{14}$.
