Question

господи,помогите блин..математика:​

Answer 1

1) 11/15X = 77

X = 77 : 11/15

X = 105

2) 23/28X = 92

X = 92 : 23/28

X = 112

3) 15/64X = 25

X = 25 : 15/64

X = 5 : 3/64 = 320/3 = 106 2/3

4) 5 1/3X = 8 8/9

16/3X = 80/9

X = 80/9 : 16/3

X= 5/3 = 1 2/3

5) 3 2/5Y = 6 4/5

17/5Y = 34/5

Y = 34/5 : 17/5

Y = 2

6) 9 1/2Y = 14 1/4

19/2Y = 57/4

Y = 57/4 : 19/2

Y = 3/2 = 1 1/2

Answer 2

Ответ:

Пошаговое объяснение:

1)

11/15х = 77

х = 77 : 11/15

х = 77 * 15/11

х = 7 * 15/1

х = 105/1

х = 105

2)

23/28х = 92

х = 92 : 23/28

х = 92 * 28/23

х = 4 * 28/1

х = 112/1

х = 112

3)

15/64х = 25

х = 25 : 15/64

х = 25 * 64/15

х = 5 * 64/3

х = 320/3

х = 106. 2/3

4)

5. 1/3х = 8. 8/9

16/3х = 80/9

х = 80/9 : 16/3

х = 80/9 * 3/16

х = 5/3 * 1/1

х = 5/3

х = 1. 2/3

5)

3. 2/5у = 6. 4/5

17/5у = 34/5

у = 34/5 : 17/5

у = 34/5 * 5/17

у = 34/17

у = 2

6)

9. 1/2у = 14. 1/4

19/2у = 57/4

у = 57/4 : 19/2

у = 57/4 * 2/19

у = 3/2 * 1/1

у = 3/2

у = 1. 1/2
