Determine the quotient: 2 4/7 ÷ 1 3/6

First we must change these numbers to improper fractions:

So then we set it up:

÷

When we divide fractions like this, we must flip the second fraction and change the sign from division to multiplication like so:

Then we solve:

Then if we divide the numerator and the denominator by 9, we get:

or, in mixed-number form, .

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
