Question

Are the following in proportion 0.45,0.9,1.8

Answer 1

Yes ,All the following are in proportion 0.45,0.9,1.8

Step-by-step explanation:

• We know that if three number like a , b , c are in proportion then

        b² = a×c       ...1)

• Given data

        There are three number which are 0.45 , 0.9 , 1.8

• So we can say that

        a = 0.45

        b = 0.9

        c = 1.8

• Now from equation 1)      

      b²           =     a×c

       0.9²        =    0.45×1.8

       0.81       =     0.81

       L. H .S    =     R. H.S

• So given number are in proportion
