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:

^{70} / _{100} = ^{Part} / _{1800}

Cross multiply:

70 x 1800 = 100 x Part, or

126000 = 100 x Part

Now, divide by 100 and get the answer:

Part = ^{126000} / _{100} = 1260

Use again the same percentage formula:

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

^{%} / _{100} = ^{70} / _{1800}

Cross multiply:

% x 1800 = 70 x 100

Divide by 1800 and get the percentage:

% = ^{70 x 100} / _{1800} = 3.8888888888889%
