Question

1,25 : x = 0,125 3,5 : x = 0,035 0,04 × x = 1,28

Answer 1

1,25 : x = 0,125
x=1.25/0.125
x=10
Ответ: х=10
==================

3,5 : x = 0,035
x=3.5/0.035
x=100
Ответ:х=100
=================

0,04 × x = 1,28
х=1,28/0,04
х=32
Ответ: х= 32 

Answer 2

To solve for x in each equation, we can use basic algebraic manipulation.

1. 1,25 : x = 0,125

To solve for x, we can cross-multiply:

1.25 * x = 0.125

Then we can divide both sides by 1.25 to isolate x:

x = 0.125 / 1.25

x = 0.1

Therefore, the solution is x = 0.1.

2. 3,5 : x = 0,035

Similar to the first equation, we can cross-multiply:

3.5 * x = 0.035

Then we can divide both sides by 3.5 to isolate x:

x = 0.035 / 3.5

x = 0.01

Therefore, the solution is x = 0.01.

3. 0,04 × x = 1,28

To solve for x, we can divide both sides by 0.04:

x = 1.28 / 0.04

x = 32

Therefore, the solution is x = 32.
