Question

(0,5х-1):1/4=1,8х-3                                                          

Answer 1

$(0,5x-1):\frac{1}{4}=1,8x-3\\\\4(0,5x-1)=1,8x-3\\\\2x-4=1,8x-3\\\\0,2x=1\\\\x=5$

Answer 2

I assume you're trying to solve the equation:

(0.5x - 1) / (1/4) = 1.8x - 3

First, let's simplify the left-hand side by multiplying both sides by the denominator of the fraction on the left-hand side (which is the same as dividing by the numerator of the fraction on the right-hand side):

0.5x - 1 = (1/4) * (1.8x - 3)

0.5x - 1 = 0.45x - 0.75

Now, we can solve for x:

0.5x - 0.45x = 1 - 0.75

0.05x = 0.25

x = 5

Therefore, the solution to the equation is x = 5.
