Question

determine if the following ratios form a proportion also write the middle terms and extreme terms where the ratios form a proportion. a) 25cm :1c​

Answer 1

∵1 m=100 cm

∴25 cm:1 cm=25 cm:100 cm

=  

100

25

​

=  

100÷25

25÷25

​

 

[H.C.F of 25,100=25]

=  

4

1

​

=1:4

Rs 40:Rs 160=  

160

40

​

=  

160÷40

40÷40

​

 

$$

[H.C.F of 40,160=40]

=  

4

1

​

=1:4

Since, the two ratio are equal therefore, the given ratios form a proportion. Middle terms are 1 m and Rs 40

Extreme terms are 25 cm and Rs 160.Answer:
