Answer 1

Ответ:

1)x/4=11/36+4/9

x/4=11/36+16/36

x/4=27/36=3/4

x=3/4×4

x=3

2)x/75=11/25+1/15

x/75=33/75+5/75

x/75=38/75

x=38/75×75

x=38

3)x/48=5/16+1/3

x/48=15/48+16/48

x/48=31/48

x=31/48×48

x=31

Answer 2

Пошаговое объяснение:

1)

х/4 - 4/9 = 11/36

х/4 = 11/36 + 4/9

х/4 = 11/36 + 16/36

х/4 = 27/36

х/4 = 3/4

х = 3/4 * 4

х = 12/4

х = 3

2)

х/75 - 1/15 = 11/25

х/75 = 11/25 + 1/15

х/75 = 33/75 + 5/75

х/75 = 38/75

х = 38/75 * 75

х = 38/1 * 1

х = 38/1

х = 38

3)

5/16 + 1/3 = х/48

15/48 + 16/48 = х/48

31/48 = х/48

- х/48 = - 31/48

х = -31/48 * (-48)

х = 31/1 * 1

х = 31/1

х = 31
