Question

15(3/5(-0,5)-1/3(2)-18(2/9*2-5/18(-0,5)=

Answer 1

0,188385 или 37677/200000

Answer 2

Let's break down the expression step by step:

1. Calculate the value inside the parentheses for each fraction:

   • $3/5 \cdot (-0.5) = -0.3$
   • $1/3 \cdot 2 = 0.666...$ (repeating decimal)
   • $2/9 \cdot 2 = 0.444...$ (repeating decimal)
   • $5/18 \cdot (-0.5) = -0.138...$ (repeating decimal)

2. Substitute these values back into the expression: $15(-0.3) - 0.666... - 18(0.444...) - 0.138...$

3. Continue simplifying: $-4.5 - 0.666... - 8.0 - 0.138...$

4. Add the decimal values: $-4.5 - 0.666... - 8.0 - 0.138... = -13.304...$ (repeating decimal)

So, the value of the expression is approximately $-13.304...$. The ellipsis (...) indicates that the decimals are repeating. If you need a more accurate decimal approximation, you can use a calculator or a computer program to get a better approximation of the repeating decimals.
