In converting 9 yards to inches, what unit (omit the number) would you place in the numerator of your ratio? Use the plural form in your answer. Remember that there are 36 inches in 1 yard.

Respuesta :

Let
X/Y--------> the ratio

we know that
 
X/Y units --------> are inches/yards
9 yards*(X/Y ) inches/yards-------> 9*X/Y yards*inches/yards----> 9*X/Y inches
the ratio in this problem is (X/Y inches /yards)-------> 36/1 inches/yards
the unit in the numerator of the ratio is inches

the answer is 
inches
