Question

ajutor la 6 urgent ze poate face?

Answer 1

6)

m=?

n=?

n-m=36

m=n:7

metoda grafica:

n /---/---/---/---/---/---/---/

m /---/

n-m [..............................] = 36

6 segmente=36

1 segment=36:6=6

m = 6

n = mx7 = 6x7 = 42

sau:

n-m=36

m=n:7=n/7

n-n/7=36

6n/7=36

6n=252

n=252:6=42
n=42

m=n:7=42:7=6
m=6
