Hey there - listen - all you need to know are the ratios between inches and centimeters - then you'll be able to answer all of your questions in 1 minute - SO:
Just remember this:
1 inch is EXACTLY 2.54cm
1 meter is 100cm (same way as 1 dollar = 100 cents)
That's ALL:
And this will give you:
(A) 7m = 700cm = 700/2.54inch = 275.6 inch
(B) 36inch = 36 * 2.54cm = 91.44cm
(C) 40cm = 40/2.54 inches - so simple! = 15.74inch
and you know what?
by now I think you can do the remaining two!
Cheers!
Shai.

x ft=7m 3.2808 x 7= 26.656 ft
36 in= y centimeters 2.54 x 36=91.44 cm
x inches= 40 centimeters 0.3937 in= 1 cm
40 x 0.3937= 15.748 in
x inches= 15 centimeters 15 x 0.3937=5.9055 in
0.8 inches=y centimeters 2.54 x0.8=2.032 in.

To express a quantity in different units, you need conversion factors.
In question E you want to convert inches into centimeters. The relation between inches and centimeters is
          1in = 2.54cm
This gives you two conversion factors:
          1in/2.54cm
and
          2.54cm/1in
All you have to do is multiply 0.8in by one of the conversion factors. Which one? The one that leaves you with cm in the numerator.
          0.8in · (2.54cm/1in) = 2.032cm
(Note that the inch units get canceled out, leaving just cm units.)
-----------
Question D is the opposite; you need to convert 15cm into inches. Use (1in/2.54cm) for your conversion factor:
          15cm · (1in/2.54cm) = 5.9in

There are 2.54 cm in an inch.
A. 7 m = 700 cm
700 cm = 275.59 in
275.59 in = 22.96 ft.
x= 22.96
B. 36 x 2.54 = y
y=91.44
C. 40 cm/ 2.54=x
x=15.74
D. 15/2.54=x
x= 5.9
E. .8x2.54=y
y=2.032
Good luck.
