Answer 1

Hola...

1) a/6= b/12, a+b = 15

a+(2a) =15

3a= 15

a= 5

b= 10

2).X/10= y/25, X+Y = 14

25X/10=y

X+25 /10=14

10x+25x=140

35x = 140

X= 140/35=4

Y= 10

3)2/c =14/d,c+ d= 40

d=14c/2= 7c

c+7c = 40

8c=40,

c = 5

d = 35

4) e/3 =f/15= g/30, e+f=32

f=15e/3 =5e

e+5e= 32

6e=32

e=5,33

f=26,66
