Question

0,25:0,4=1,35:(0,3х)

Answer 1

0,25:0,4=1,35:(0,3х)

0,25*0,3x=1,35*0,4

0,075x=0,54

x=0,54/0,075

x=7,2

Answer 2

To solve the equation, we need to find the value of "x" that satisfies the equation:

0.25 : 0.4 = 1.35 : (0.3 * x)

First, let's simplify the left-hand side of the equation:

0.25 : 0.4 = 0.625

Now, our equation becomes:

0.625 = 1.35 : (0.3 * x)

Next, let's solve for "x". To do that, we'll cross-multiply:

1.35 * x = 0.3 * 0.625

Now, calculate the right-hand side:

1.35 * x = 0.1875

Finally, isolate "x" by dividing both sides by 1.35:

x = 0.1875 / 1.35 x = 0.1388888889

Therefore, the value of "x" that satisfies the equation is approximately 0.1389 (rounded to four decimal places).
