The first thing you should do for this case is to know the result of each fraction.
We have then:
19/50 = 0.38
13/20 = 0.65
Then, to know the percentage, we must multiply this value by 100.
0.38 * 100 = 38%
0.65 * 100 = 65%
answer
the equivalent percent for each fraction are
38%
65%
respectively

The equivalent percent for the given fractions are 38% (19/50 * 2/2 = 38/100) and 65% (13/20 * 5/5 = 65/100). To calculate the percentage the goal is to get the denominator to be 100, so we can multiply by forms of 1 and just multiply across the numerator and denominator.

750 ÷ 1/2
750/1 ÷ 1/2
750/2
