First, we need to convert all the givens to decimal numbers. This will ease the arrangement process. 0.43 is already given as a decimal 3/7 is equal to 0.428 43.8% is equal to 0.438 7/16 is equal to 0.4375
Now, it has become easy to arrange the givens from smallest to biggest as follows: 0.428 , 0.43 , 0.4375 , 0.438
Changing the decimals back to the given form, we will find that the arrangement from the smallest to the biggest is as follows: 3/7 , 0.43 , 7/16 , 43.8%
