Question

1) х:18=56:14 2) 21:х=7:8 3) 40:10=х:2 4) 16:5=64:х 5) х:6=25:15

Answer 1

Пошаговое объяснение:

1)

х : 18 = 56 : 14

14 * х = 56 * 18

14х = 1008

х = 1008 : 14

х = 72

2)

21 : х = 7 : 8

7 * х = 8 * 21

7х = 168

х = 168 : 7

х = 24

3)

40 : 10 = х : 2

10 * х = 40 * 2

10х = 80

х = 80 : 10

х = 8

4)

16 : 5 = 64 : х

16 * х = 5 * 64

16х = 320

х = 320 : 16

х = 20

5)

х : 6 = 25 : 15

15 * х = 25 * 6

15х = 150

х = 150 : 15

х = 10

Answer 2

Let's solve the given equations one by one:

1. х:18 = 56:14

To solve this equation, we can cross-multiply:

14 * х = 56 * 18

Simplifying the equation:

14х = 1008

Dividing both sides by 14:

х = 72

So, the solution to this equation is х = 72.

2. 21:х = 7:8

To solve this equation, we can cross-multiply:

7 * х = 21 * 8

Simplifying the equation:

7х = 168

Dividing both sides by 7:

х = 24

So, the solution to this equation is х = 24.

3. 40:10 = х:2

To solve this equation, we can cross-multiply:

10 * х = 40 * 2

Simplifying the equation:

10х = 80

Dividing both sides by 10:

х = 8

So, the solution to this equation is х = 8.

4. 16:5 = 64:х

To solve this equation, we can cross-multiply:

5 * 64 = 16 * х

Simplifying the equation:

320 = 16х

Dividing both sides by 16:

х = 20

So, the solution to this equation is х = 20.

5. х:6 = 25:15

To solve this equation, we can cross-multiply:

15 * х = 25 * 6

Simplifying the equation:

15х = 150

Dividing both sides by 15:

х = 10

So, the solution to this equation is х = 10.

To summarize:

1. х = 72
2. х = 24
3. х = 8
4. х = 20
5. х = 10
