Question

cat de repede se poate te rog !dau coroana ,..!!!​

Answer 1

a)3/2- 1/3: (1/5+1/15) = 3/2 - 1/3 : 4/15= 3/2-5/4 = 1/4

b) -1/4+(-3/2)² -9/5:(-18/20) = -1/4 + 9/4 - 9/5 : 9/10 = 1/4+9/4 - 2 = 1/2

c)6:(5/2-2/5)+11/30:1 2/3+(-1)²⁰⁰⁵ = 6: 21/10+11/50+ (-1)²⁰⁰⁵= 33/25

d) -2 2/3 • ( - 7/12 + 1 1/3 - 3/8 ) = -2 2/3• 3/8 =1

e) (- 8/15 + 3/10) : ( -14 /15 ) +( - 2/9+ 1 /12):(-5/9) = 7/30 : -0, 933333+ -7/12: 0,555556= - 505555487500/ 388889061111

SPER CA TE AM AJUTAT p.s sunt in cls a 5 a =))))) si chiar m-am straduit sa fie corect
