Question

Se considera un punct M pe segmentul [AB]. Stiind ca AB=10 cm si AM=2 cm,calculati valoarea rapoartelor:
a)$\frac{MB}{AM}$
b)$\frac{MB}{AB}$
c) $\frac{AM}{AB}$

Answer 1

a) MB /AM
Stim ca AB =AM+MB
10=2cm+MB 
MB=10-2 =8cm
MB=8cm
MB/AM =   8cm/  2 cm =4 cm
b)MB /AB
8cm / 10 cm, simplificam prin 2 =>raportul e egal cu 4/ 5
c)AM/AB
2 / 10 , simplificam prin 2 si obtinem : 1/5

Answer 2

AB=10cm;AM=2cm;MB=AB-AM=10-2=8cm→MB=8cm
a)MB/AM=8/2=4
b)MB/AB=8/10=4/5
c)AM/AB=2/10=1/5
