Using each of the digits 0-6 only once, make two equivalent ratios (also known as a proportion).

Step-by-step explanation:

-The digits between 0-6 are:

#We form the first ratio:

#Multiplying both the denominator and numerator in the first ratio gives an equivalent ratio whose digits lie between 0-6:

Simplifying the second ratio gives you the first ratio.

Hence, the two equivalent ratios are:

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
