Question

А) 5/36+ × = 5/9

Б) 18/15 : × = 8/45

Answer 1

А)5/36+x=5/9
x=5/9-5/36=20/36-5/36=15/36
x=5/12
5/36+5/12=5/9
Ответ:x=5/12

Б)18/15:x=8/45
x=18/15:8/45=18/15*45/8=9/1*3/4=27/4
x=6 3/4
18/15:6 3/4=8/45
Ответ:x=6 3/4

Answer 2

5/36+ x = 5/9
x=5/9-5/36
x=(20-5)/36
x=15/36
x=5/12

18/15 : x = 8/45
x= 18/15 : 8/45
x= (18*45)/(15*8)
x=54/8
x= 6 6/8
