Answer 2

Пошаговое объяснение:

7 3/11×4 3/5+2 8/11×4 3/5=4 3/5× (7 3/11+2 8/11)=4 3/5×10=23/5×10=46

Answer 3

To calculate the expression $7 \frac{3}{11} \cdot 4 \frac{3}{5} + 2 \frac{8}{11} \cdot 4 \frac{3}{5}$, follow these steps:

Step 1: Convert mixed numbers to improper fractions. $7 \frac{3}{11} = \frac{7 \cdot 11 + 3}{11} = \frac{77 + 3}{11} = \frac{80}{11}$ $4 \frac{3}{5} = \frac{4 \cdot 5 + 3}{5} = \frac{20 + 3}{5} = \frac{23}{5}$ $2 \frac{8}{11} = \frac{2 \cdot 11 + 8}{11} = \frac{22 + 8}{11} = \frac{30}{11}$

Step 2: Perform the multiplications and additions. $\frac{80}{11} \cdot \frac{23}{5} + \frac{30}{11} \cdot \frac{23}{5} = \frac{80 \cdot 23}{11 \cdot 5} + \frac{30 \cdot 23}{11 \cdot 5} = \frac{1840}{55} + \frac{690}{55}$

Step 3: Add the fractions. $\frac{1840}{55} + \frac{690}{55} = \frac{1840 + 690}{55} = \frac{2530}{55}$

Step 4: Simplify the fraction, if possible. To simplify the fraction, you can find the greatest common divisor (GCD) of 2530 and 55, which is 5.

$\frac{2530}{55} = \frac{2530 \div 5}{55 \div 5} = \frac{506}{11}$

So, the final result is $\frac{506}{11}$.
