Question

9/27 : 80/27 = 0,9 : x

Answer 1

9/80 = 0,9/х
х = (80 * 0,9) / 9 = 8 (т.к. 0,9 и 9 сокращаются)

Answer 2

To solve the equation, let's first simplify the left-hand side by dividing 80 by 27:

80 ÷ 27 = 2.96296...

Now, we have the equation: 0.9 : x = 2.96296...

To find the value of x, we can cross-multiply and solve for x:

0.9 * x = 2.96296...

Dividing both sides by 0.9:

x = (2.96296...) / 0.9

Calculating the right-hand side:

x ≈ 3.29107...

Therefore, approximately, 0.9 : x ≈ 2.96296... : 3.29107...
