Question

If(10x+3y):(5x+2y)=9:5,let us show that,(2x+y):(x+2y)=11:13

Answer 1

Answer:

(2x+y):(x+2y)=11:13

(2(6)+10):(6+2(10))=11:13

(12+10):(6+20)=11:13

divide by two->(22):(26)=11:13

(11):(13)=11:13

Step-by-step explanation:

x=6

y=10

(10x+3y):(5x+2y)=9:5

(10x+3y):(5x+2y)=90:50,<--multiply by ten

(10(6)+3(10)):(5(6)+2(10))=90:50

(60+30):(30+20)=90:50

(90):(50)=90:50

(2x+y):(x+2y)=11:13

(2(6)+10):(6+2(10))=11:13

(12+10):(6+20)=11:13

divide by two->(22):(26)=11:13

(11):(13)=11:13
