Answer 1

Make the denominator of each fraction 100 so it will be easier to compare:
\(\Large \frac{13}{25}, ~~ 0.45, ~~ \frac{43}{100}, ~~ \frac{29}{50}\) can be rewritten as:

\(\Large \frac{13*4}{25*4}, ~~ \frac{45}{100}, ~~ \frac{43}{100}, ~~ \frac{29*2}{50*2}\) =

\(\Large \frac{52}{100}, ~~ \frac{45}{100}, ~~ \frac{43}{100}, ~~ \frac{58}{100}\)

Since the denominators are all the same, the fraction with the highest numerator is the greatest number.
