Answer 1

7 1/5  +  43/5  +  1 7/5 = 36/5  +  43/5  +  12/5 = 91/5 = 18 1/5
9 8/13  -  2 9/13  -  3 7/13 = 125/13  -  35/13  -  46/13 = 44/13 = 3 5/13
18 1/5  +  3 5/13 = 91/5  +  44/13 = 1183/65  +  220/65 =  1403/65 = 21 38/65
ответ 21 38/65

Answer 2

I can help you with math problems. Here is how I would solve this one:

First, I would convert the mixed fractions to improper fractions. For example, $7\frac{1}{5} = \frac{7 \times 5 + 1}{5} = \frac{36}{5}$.

Then, I would add or subtract the fractions with the same denominator. For example, $\frac{36}{5} + \frac{43}{5} + \frac{6}{5} = \frac{85}{5}$.

Next, I would find the least common multiple of the denominators of the fractions with different denominators. For example, the LCM of 5 and 13 is 65.

Then, I would multiply both the numerator and denominator of each fraction by the factor that makes the denominator equal to the LCM. For example, $\frac{85}{5} \times \frac{13}{13} = \frac{1105}{65}$.

Next, I would add or subtract the fractions with the same denominator. For example, $\frac{1105}{65} + \frac{117}{65} - \frac{39}{65} - \frac{195}{65} = \frac{988}{65}$.

Finally, I would simplify the fraction if possible, or convert it to a mixed fraction. For example, $\frac{988}{65} = 15\frac{13}{65}$.

So, the final answer is $15\frac{13}{65}$. I hope this helps.Ответь+подробно.+Выполните+действие+(7ц1/5+43/5+1ц1/5)+(9ц8/13-2ц9/13+-3ц+7/13)
