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:

^{2.6} / _{100} = ^{Part} / _{2.99}

Cross multiply:

2.6 x 2.99 = 100 x Part, or

7.774 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{7.774} / _{100} = 0.07774

Use again the same percentage formula:

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

^{%} / _{100} = ^{2.6} / _{2.99}

Cross multiply:

% x 2.99 = 2.6 x 100

Divide by 2.99 and get the percentage:

% = ^{2.6 x 100} / _{2.99} = 86.95652173913%
