Question

решите уравнение: а) 4*25*x=800; б) y*5*20=500; в) 21*8*p=168; г) m*3*33=990

Answer 1

$4 times 25 times x = 800 \ 100x = 800 \ x = 800 div 100 \ x = 8$
▪б)

$y times 5 times 20 = 500 \ 100y = 500 \ y = 500 div 100 \ y = 5$
▪в)

$21 times 8 times p = 168 \ 168p = 168 : : : : : | div 168 \ p= 1$
▪г)

$m times 3 times 33 = 990 \ 99m = 990 : : : : : | div 99 \ m = 10$
