Answer:
Sandhya performed better.
Step-by-step explanation:
You can either or simplify the fractions:
[tex]\frac{630}{900}[/tex] and [tex]\frac{650}{1300}[/tex] to simpler forms like [tex]\frac{7}{10}[/tex] and [tex]\frac{1}{2}[/tex] from there you can make the [tex]\frac {1}{2}[/tex] and multiply it by [tex]\frac{5}{5}[/tex] to get [tex]\frac{5}{10}[/tex] and then from there you can see Sandya performed better.
OR
You can divide 630 by 900 and 650 by 1300
630/900 gives you 70
and
650/1300 gives you 50
Clearly, once again Sandhya performed better.
