Question

se considera[AB] de 48 cm si M∈(AB).Calculati AM si MB daca AM supra MB = 3 supra 5

Answer 1

AM/MB=3/5⇒AM=3K⇒AM=3*6=18cm
                     MB=5K⇒MB=5*6=30cm
AB=AM+MB=3K+5K=8K
48=8K⇒48/8=6

Answer 2

AM+MB=AB 
AB=48 DECI AM+MB=48
AM/MB=3/5 DECI 5AM=3MB DECI AM=3/5MB
ACUM AM+MB=48
INLOCUIM AM SI O SA AVEM: 3/5MB+MB=48
ADUCEM LA ACELASI NUMITOR : 3 MB+ 5MB= 48 ori 5
8 MB= 240 REZULTA MB= 240/8 DECI MB=30
ACUM AM+MB=48 SI MB=30
DECI AM+30=48 REZULTA AM= 48-30 DECI AM=18
