Answer:
1,005.84 cm
Step-by-step explanation:
Given the unit fractions, 36 in/1 yd (i.e. 36 inches = 1 yard), and 2.54 cm/1 in (i.e. 2.54 cm = 1 inches), to convert 11 yd to cm, first convert to inches, then convert what you have in inches to cm.
Thus:
Converting 11 yd to inches:
36 in = 1 yd
11 yd = 36*11 = 396 in
Converting 396 in to cm:
2.54 cm = 1 in
396 in = 2.54*396 = 1,005.84 cm
When you solve a proportion, your first step should be to cross-multiply.

=

When you cross-multiply, you should get this equation:
(2x)(3) = (x + 3)(5)
Now, solve it using algebra.
(2x)(3) = (x + 3)(5) Multiply
6x = 5x + 15 Subtract 5x from both sides
x = 15
The value of
x is 15.
