Question

Решите пожалуйста по действиям и столбиком если можно (-2,04:1/25-3,61:(-19/40)):(-2 4/5)+0,6:(-0,9)

Answer 1

(-2,04:1/25-3,61:(-19/40)):(-2 4/5)+0,6:(-0,9)=
=(-2,04:0,04 -3,61:(-0,475)):(-2,8)+0,6:(-0,9)=
= (-51 + 7,6):(-2,8) - 2/3 = -43,4 :(-2,8) -2/3 = 15,5 - 2/3= 15 3/6 - 4/6 = 14 5/6

Answer 2

I will try to answer your question in detail. To solve this expression, you need to follow the order of operations: parentheses, exponents, multiplication and division, and addition and subtraction. You also need to know how to perform arithmetic operations with fractions and decimals. Here is one possible solution:

(-2,04:1/25-3,61:(-19/40)):(-2+4/5)+0,6:(-0,9)

First, we simplify the fractions inside the parentheses by finding the common denominator and adding or subtracting the numerators:

(-2,04:1/25-3,61:(-19/40)):(-2+4/5)+0,6:(-0,9) = (-2,04:1/25-3,61:(-19/40)):(-10/5+4/5)+0,6:(-0,9) = (-2,04:1/25-3,61:(-19/40)):(-6/5)+0,6:(-0,9)

Next, we perform the division operations inside the parentheses by multiplying the first number by the reciprocal of the second number:

(-2,04:1/25-3,61:(-19/40)):(-6/5)+0,6:(-0,9) = (-2,04*25-3,61*(-40/19)):(-6/5)+0,6:(-0,9) = (-51-7,6/19):(-6/5)+0,6:(-0,9)

Then, we subtract the numbers inside the first parentheses by converting them to decimals and rounding to two decimal places:

(-51-7,6/19):(-6/5)+0,6:(-0,9) = (-51-0,4):(-6/5)+0,6:(-0,9) = (-51,4):(-6/5)+0,6:(-0,9)

After that, we divide the numbers inside the second parentheses by converting them to decimals and rounding to two decimal places:

(-51,4):(-6/5)+0,6:(-0,9) = (-51,4):(-1,2)+0,6:(-0,9)

Next, we perform the division operation between the first two parentheses by multiplying the first number by the reciprocal of the second number:

(-51,4):(-1,2)+0,6:(-0,9) = (-51,4)*(-0,833)+0,6:(-0,9) = 42,8+0,6:(-0,9)

Then, we perform the division operation between the last two numbers by multiplying the first number by the reciprocal of the second number:

42,8+0,6:(-0,9) = 42,8+0,6*(-1,111) = 42,8-0,667

Finally, we add the two numbers by aligning the decimal points and adding the digits:

42,8-0,667 = 42,800 - 0,667 ------- 42,133

Therefore, the final answer is 42,133.
