Hint: The above question is based on the concept of percentage. The main approach towards solving the expression is by writing the 70 % in the percentage form i.e., fraction of 100 and then multiplying it with a number of which percentage has to be calculated.
Complete step-by-step answer:
Percent can also means one part in a hundred. Percentage is a number or ratio as a fraction of out of 100. The number of a percentage is always followed by a percent symbol (%).
The percentage is the result when a particular number is multiplied by a percent. Mostly, percentages are smaller than the number since a percentage is a portion of a number or quantity. But there are cases where the percentage is more than the number. This will happen if the percent is more than 100%.
Now to calculate the 70% of a number we will take a number for example the number is 50.
So first we divide the 70 with 100 we get
Then multiplying the above lowest form of fraction with the number 50 we get,
Therefore 70% of a number is calculated in the above way
Note: An important thing to note is that we can also write in the decimal format.It is not necessary that we multiply the number with the fraction form instead we can write it in decimal format i.e., 0.7 and multiplying 0.7 with the number of which percentage has to be calculated.
