Question

let's find how much grms is 30% of 840 grms​

Answer 1

30% of 840 = 252.

• A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The word "percent" is used to symbolise it.
• There is no dimension to percentages. As a result, it is known as a dimensionless number. We must divide the value by the entire value to find the percentage, and then multiply the resulting number by 100. The original number is subtracted from the new number, divided by the original number, then multiplied by 100 to get the % increase.

Here, according to the given information, we are given that,

30% of 840 = $\frac{30}{100}.840 = 252.$

Hence, 30% of 840 = 252.
