Proportion means “per hundred.”
The time period “proportion” is derived from the Latin phrase “per centum,” which implies “by the hundred.” In different phrases, a proportion represents part of an entire, the place the entire is taken into account to be 100.
-
Percentages are expressed as a quantity adopted by the % signal (%).
For instance, 50% means 50 out of 100, or half of the entire.
-
Percentages can be utilized to check totally different portions.
For instance, in case you say {that a} product is 20% off, it signifies that the value of the product is 20% lower than the unique value.
-
Percentages are utilized in all kinds of purposes.
Some widespread examples embrace calculating reductions, rates of interest, taxes, and examination scores.
-
Percentages could be transformed to fractions and decimals.
To transform a proportion to a fraction, merely divide the share by 100. To transform a proportion to a decimal, divide the share by 100 and transfer the decimal level two locations to the left.
Understanding the idea of percentages is important for deciphering knowledge, making comparisons, and fixing a wide range of mathematical issues. By remembering {that a} proportion represents part of an entire, you possibly can simply grasp the importance and purposes of percentages in on a regular basis life.
Categorical as a fraction of 100.
To seek out the share of one thing, we have to specific it as a fraction of 100. It’s because a proportion represents part of an entire, and the entire is taken into account to be 100.
-
To specific a proportion as a fraction of 100, merely divide the share by 100.
