Answer 4

The reciprocal of \(\sf\Large\frac{a}{b}\) is \(\sf\Large\frac{b}{a}\)

Answer 5

so like 11/12 would be 12/11?

Answer 6

The reciprocal of \(\sf x\) is \(\sf\Large\frac{1}{x}\)

Why? Because \(\sf\Large x=\frac{x}{1}\)

And using what I wrote above, you would get that.

Answer 7

Correct! :D

Answer 8

11/12 and 12/11 are reciprocals. (:

Answer 9

what about that one its a mixed fraction

Answer 10

And also do note that when you multiple reciprocals together, you should get 1

So we know that \(\sf\Large\frac{a}{b}\) and \(\sf\Large\frac{b}{a}\) are reciprocals, so then

\(\sf\Large\frac{a}{b}\times\frac{b}{a}=1\)

Answer 11

Make the mixed number into an improper fraction and then do the reciprocal of that. And if needed then you can make it back in to a mixed fraction. :)

Answer 12

so 11/4 is 4/11? :DD

Answer 13

Correct :D
