Set up a proportion, which is a comparison between two or more things.
3 feet = 1 yard
x feet = 27 yards
You are converting to smaller units. Feet are smaller than yards.
So you multiply!
27 x 3= 81.
So 81 feet = 27 yards.
You can double-check your answer by cross-multiplying.
3 ft x 81 ft
1 yard 27 yards
So you multiply diagonally; that is, multiply 1 yard by 81 ft, and 3 ft by 27 yards. The products should equal. Hooray!
Think of it as ratios.
3 : 1
x : 27
Now just make it into an equation.
3/x = 1/27
rearrange to make x the subject
x = 27 x 3
x = 81
given that 3 ft = 1 yard
multiply both sides by 27 …. the value doesnt change
3*27 ft = 1*27 yards
3*27 = 81
hence 81 ft = 27 yards….
