Решите уравнение
а)4•25•х=800
б)у•5•20=500
в)21•8•р=168
г)м•3•33=990

1) 4 * 25 * x = 800
100 * x = 800
x = 800 : 100
x = 8

2) y * 5 * 20 = 500
y * 100 = 500
y = 500 : 100
y = 5

3) 21 * 8 * p = 168
8 * p = 168 : 21
8 * p = 8
p = 8 : 8
p = 1

4) m * 3 * 33 = 990
m * 33 = 990 : 3
m * 33 = 330
m = 330 : 33
m = 10

а)4•25•х=800
25*x=800/4
25*x=200
x=200/25
x=8
4*25*8=800
800=800

б)у•5•20=500
y*5=500/20
y*5=25
y=25/5
y=5
5*5*20=500
500=500

в)21•8•р=168
8*p=168/21
8*p=8
p=8/8
p=1
21*8*1=168
168=168

г)м•3•33=990
m*3=990/33
m*3=30
m=30/3
m=10
3*10*33=990
990=990
