Ответ:
1) 8/14=х/35=40 т.к. х=8*35/14=4*5
2) 7/28=x/12=3 т.к. x7*12/28=1*3=3
3) 4/x=6/18=12 т.к. x=4*18/6=4*3=12
4) 14/10=21/x=15 т.к. x=10*21/14=5*3=15
5) x/10=18/60=3 т.к. x=10*18/60=1*3=3
6) 45/25=18/x=10 т.к. x=25*18/45=5*2=10
Пошаговое объяснение:
1) 8/14 = х/35
x = (8 * 35)/14
x = 20
2) 7/28=x/12
x = (7 * 12)/28
x = 3
3) 4/x=6/18
x = (4 * 18)/6
x = 12
4) 14/10=21/x
x = (10 * 21)/14
x = 15
5) x/10=18/60
x = (10 * 18)/60
6) 45/25=18/x
x = (25 * 18)/45
x = 10
