Пошаговое объяснение:

$3\frac{3}{11}:18+100:\frac{25}{36}-5\frac{1}{6}:\frac{11}{30}=\\ 1)\frac{36}{11}:\frac{18}{1}=\frac{36}{11}*\frac{1}{18} =\frac{2}{11}\\2)\frac{100}{1}:\frac{25}{36}=\frac{100}{1} *\frac{36}{25}=144\\ 3)\frac{31}{6}:\frac{11}{30} =\frac{31}{6}*\frac{30}{11}=\frac{155}{11}\\ 4)\frac{2}{11}+144 =144\frac{2}{11} \\ 5)144\frac{2}{11}- \frac{155}{11}=\frac{1586}{11}-\frac{155}{11}=\frac{1431}{11}= 130\frac{1}{11}$

Answer 2

To solve this expression, let's break it down step by step:

1. Convert mixed numbers to improper fractions:

   • 3 3/11 = (11 * 3 + 3) / 11 = 36/11
   • 5 1/6 = (6 * 5 + 1) / 6 = 31/6
   • 1 1/30 = (30 * 1 + 1) / 30 = 31/30

2. Perform arithmetic operations:

   • 36/11 : 18 = (36/11) / 18 = 2/11
   • 100 : 25/36 = 100 * (36/25) = 144
   • 31/6 : 31/30 = (31/6) * (30/31) = 5

Now, putting it all together:

• 2/11 + 144 - 5 = 141 - 5 = 136

So, the result of the expression is 136.
