So we're looking for the top half of a fraction. They all appear to equal to 5/10, which is 1/2. Whatever is 1/2 of the denominator (or twice the numerator) is our answer. ?/100; 1/2 of 100 is 50, that answer is 50/100. 3/?; 3 is 1/2 of the denominator, multiply by 2. 3/6. 2/?; multiply by 2. 2/4. ?/10; divide by 2, 5/10. Hope this helps!
