One yard is approximately 0.91 meter. Write a direct variation equation that relates x yards to y meters.

Question

Help me with math

Answer 1

x = 0.91 y

y = (1/0.91) x

those are approximations

but actually one inch = exactly 2.54 centimeters, so

36 inches = exactly one yard = 36(2.54) centimeters = exactly 91.44 cm = exactly 0.9144 meters

so

x = (exactly) 0.9144 y
