The first equation is correct, as 7.2/36 simplifies to 8/40.

However, the second equation is incorrect. To simplify 7.07/101, we would need to find an equivalent fraction with a denominator of 400. To do this, we would multiply both the numerator and the denominator by 4 (100 x 4 = 400). This gives us:

7.07/101 * 4/4 = 28.28/404

Therefore, 7.07/101 is equal to 28.28/404.
