Пошаговое объяснение:

$4*1\frac{1}{2} +1\frac{23}{25} :\frac{3}{20} \\1)4*1\frac{1}{2} =\frac{4}{1} *\frac{3}{2} =\frac{6}{1} =6\\2)1\frac{23}{25} :\frac{3}{20} =\frac{48}{25} :\frac{3}{20} =\frac{48}{25} *\frac{20}{3} =\frac{64}{5} =12\frac{4}{5} =12.8\\3)6+12.8=18.8$

Answer 2

To solve the expression you provided, let's break it down step by step:

Step 1: Evaluate the multiplication 4 × 1 = 4

Step 2: Evaluate the addition 1 1/2 + 1 = 2 1/2

Step 3: Convert the mixed number to an improper fraction 2 1/2 = (2 × 2 + 1) / 2 = 5/2

Step 4: Convert the mixed number 23_25 to an improper fraction 23 25/100 = (23 × 100 + 25) / 100 = 2325/100

Step 5: Evaluate the division 3 20/2325/100 = (3 + 20/2325/100)

Now, to solve the expression involving fractions, we need to find a common denominator. In this case, the common denominator is 100. Let's convert both fractions to have a denominator of 100.

20/2325/100 = (20 × 100) / 2325 = 2000/2325 = 40/47

Step 6: Evaluate the division 3 + 40/47 = (3 × 47 + 40) / 47 = (141 + 40) / 47 = 181/47

Finally, the value of the expression is 181/47.
