Question

Calculati 11 și 13 va rog coroniță îmi trebuie acum

Answer 1

1/15-5/6+1/9⇒c.m.m.m.c=90⇒(6-15+10)/90⇒1/90
11/8+7/3-(11/8+7/3)⇒11/8+7/3-11/8-7/3=0
2/10+0-6/5⇒(2-12)/10=-1
(143*37+5)/37-(143*37+4)/37=(5296-5295)/37=1/37
procedand la fel ⇒-1/37
numitorul comun e 6x⇒0/6x=0

2²-(49+9)/25⇒4-58/25⇒(100-58)25⇒42/25
1-5.3=-4.3
3/6[(9+18-36)/36]=3/6*(-9/12)=-3/4
(7⁶):(7)⁸=7⁻²
2/13(1-31)=-60/13
