Пошаговое объяснение:
1/ 576÷9=8*x
x = 576÷9÷8
x = 8
2/ 252÷6=6*x
x = 252÷6÷6
x = 7
3/ 4*56=x÷56
x= 4*56*56
x = 12544
4/ 21*12=x÷21
x = 21*12*21
x = 5292
5/ 24*35=840÷x
x = 840÷(24*35)
x = 1
6/ 900÷15=4*x
x = 900÷15÷4
x = 15
1) 0.4 * 30 =12
2) 0.5 * 18 = 9
3) 0.1 * 6.5 = 0.65
4) 2.5 * 40 = 100
5) 0.12 * 100 = 12
6) 0.01 * 1000 = 10.
