Question

Математика 6 класс найдите значение выражения (7 3/5*(-2,5)-4 3/20*(-10)*(2-3 4/25)

Answer 1

7 3/5*(-2,5)=-19
4 3/20*(-10)=-41 1/2
2-3 4/5=-1 4/5
41 1/2*(-1 4/5)=74 7/10
-19-74 7/10=-19 7/10

Answer 2

Незнаю насколько верно )))

Answer 3

I can help you with math problems. To find the value of the expression, you need to follow the order of operations: parentheses, exponents, multiplication and division, and addition and subtraction. Here is a step-by-step solution:

$$ \begin{aligned} (7+\frac{3}{5}(-2,5)-4+\frac{3}{20}(-10)(2-3+\frac{4}{25})) &= (7-\frac{15}{10}-4-\frac{30}{20}(2-\frac{79}{25})) \\ &= (7-\frac{3}{2}-4-\frac{3}{2}(-\frac{23}{25})) \\ &= (7-\frac{3}{2}-4+\frac{69}{50}) \\ &= (\frac{35}{5}-\frac{15}{10}-\frac{20}{5}+\frac{69}{50}) \\ &= (\frac{70}{10}-\frac{15}{10}-\frac{40}{10}+\frac{69}{50}) \\ &= (\frac{15}{10}+\frac{69}{50}) \\ &= (\frac{75}{50}+\frac{69}{50}) \\ &= \frac{144}{50} \\ &= 2.88 \end{aligned} $$

The value of the expression is 2.88. I hope this helps.Ответь+подробно.+Математика+6+класс+найдите+значение+выражения+(7+3/5*(-2,5)-4+3/20*(-10)*(2-3+4/25)
