Answer 2

The value of A ,B and C are 1.5 , 5 and 10.5

Step-by-step explanation:

using the direct method

let the blank spaces be A , B, C as shown in the figure

then

$\frac{1}{A} = \frac{3}{4.50}\\\\3A = 4.50\\A = \frac{4.50}{3} \\A= 1.5$

Then ,

$\frac{3}{4.50} = \frac{B}{7.50} \\4.50B = 3\times 7.50\\B = \frac{22.5}{4.5} \\B = 5$

Then ,

$\frac{5}{7.50} = \frac{7}{C}\\ 5C= 7\times 7.50\\C = \frac{52.5}{5}\\ C= 10.5$

hence ,

The value of A ,B and C are 1.5 , 5 and 10.5
