Question

VA ROG MULT EX: 11 b,c si EX:12 a. IMI TREBUE URGENT!!!!!!!!!!!!!!!!!!!!!!!!

Answer 1

11b)
a=2m
b=3m
c=6m
d=7m

a+b+c+d=360

2m+3m+6m+7m=360

18m=360

m=20

a=40
b=60
c=120
d=140

11c)

a=6m
b=8m
c=10m
d=12m

a+b+c+d=360

6m+8m+10m+12m=360

36m=360

m=10

a=60
b=80
c=100
d=120

12a)

a=(1/2)m
b=(1/3)m
c=(1/6)m
d=(1/9)m

a+b+c+d=360

(1/2)m+(1/3)m+(1/6)m+(1/9)m=360

Inmultim cu 18:

9m+6m+3m+2m=360x18

20m=360x18

Impartim la 20

m=18x18=324

a=162
b=108
c=54
d=36
