Va rog frumos sa ma ajutati sa dau coronita si 100 puncte

Answer 1

a) (1/3+25/100)×/7+5/7= (1/3+1/4)×12/7= /4+3/12×12/7= 7/12×12/7=1

b) 0.5+0.5×1/3=5/10+5/10×1/3= 1/2+1/2×1/3= 1/2+1/6= /3+1/6=4/6=2/3

c) 375/1000×(25/100+1/6)×(2/10+1/3)= 375/1000×(1/4+1/6)×(1/5+1/3)= 375/1000×/3+2/12×/3+5/15= 375/1000×5/12×8/15= 25/200×1/3×2= 1/8×1/3×2= 1/4×1/3= 1/12

d)1.25÷1.25-3.3×0.3+0.16= 1-0.99+0.16=0.17

c)1.6÷/9-5/3+5/10×1/3-0= 1.6÷4/3+1/2×1/3= 1.6×3/4+1/6= 1.6×0.75+1/6= 1.2+1/6= 12/10+1/6= 6/5+1/6=/36+5/30= 41/30
