Answer 2

Sure, let's solve these math expressions step by step:

1. $4 \frac{2}{9} \times 2 \frac{4}{7} + 1 \frac{2}{9} \times 4 \frac{4}{7}$

First, let's convert the mixed numbers to improper fractions: $4 \frac{2}{9} = \frac{41}{9}$ $2 \frac{4}{7} = \frac{18}{7}$ $1 \frac{2}{9} = \frac{11}{9}$ $4 \frac{4}{7} = \frac{32}{7}$

Now we perform the multiplications: $\frac{41}{9} \times \frac{18}{7} + \frac{11}{9} \times \frac{32}{7}$

$\frac{738}{63} + \frac{352}{63}$

Now add the fractions: $\frac{738 + 352}{63}$

$\frac{1090}{63}$

Now divide the numerator by the denominator: $1090 \div 63 = 17 \frac{29}{63}$

So, the result of the first expression is $17 \frac{29}{63}$.

2. $2 \frac{5}{6} \times 6 \frac{2}{3} + 6 \frac{2}{3} - 6 \frac{2}{3} \times 1 \frac{1}{3}$

First, let's convert the mixed numbers to improper fractions: $2 \frac{5}{6} = \frac{17}{6}$ $6 \frac{2}{3} = \frac{20}{3}$ $6 \frac{2}{3} = \frac{20}{3}$ $1 \frac{1}{3} = \frac{4}{3}$

Now perform the operations: $\frac{17}{6} \times \frac{20}{3} + \frac{20}{3} - \frac{20}{3} \times \frac{4}{3}$

$\frac{340}{18} + \frac{60}{3} - \frac{80}{9}$

Simplify the fractions: $\frac{340}{18} + 20 - \frac{80}{9}$

$\frac{170}{9} + 20 - \frac{80}{9}$

Now add and subtract the fractions: $\frac{170 + 180 - 80}{9}$
