Answer 1

B) 7+5/6=12/6=2/3 (simplificand prin 2)
C) 15/13+12=15/25=3/5 (simplificand prin 5)
D) 30+20/30=50/30=5/3 (simplificand prin 10)
E) 20+30+40/10+20+30=90/60=3/2 (simplificand prin 30)
F) 1+2+3+4/2+4+6+8=10/20=1/2 (simplificand prin 10)
G) 1x2x3x4x5/2×4×6×8×10=120/3840= 1/192 (simplificand prin 120)
