See the solutions to these problems just after the percentage calculator below.

Here are the solutions to the questions stated above:

Always use this formula to find a percentage:

^{%} / _{100} = ^{Part} / _{Whole} replace the given values:

^{9.7} / _{100} = ^{Part} / _{21}

Cross multiply:

9.7 x 21 = 100 x Part, or

203.7 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{203.7} / _{100} = 2.037

Use again the same percentage formula:

^{%} / _{100} = ^{Part} / _{Whole} replace the given values:

^{%} / _{100} = ^{9.7} / _{21}

Cross multiply:

% x 21 = 9.7 x 100

Divide by 21 and get the percentage:

% = ^{9.7 x 100} / _{21} = 46.190476190476%
