One-fourth of the world's population is Chinese and one-fifth of the rest is Indian. What percent of the world's population is Indian?
What is 1/5 of 3/4 ?
20%
1/4 of population is Chinese, so 3/4 is not
1/5 of those 3/4
= 3/20
= .15
= 15%
To find the percentage of the world's population that is Indian, we need to calculate the total percentage of Indians based on the given information.
First, we know that one-fourth (1/4) of the world's population is Chinese. This means that the remaining three-fourths (3/4) are not Chinese.
Next, we are told that one-fifth (1/5) of the remaining population (i.e., the three-fourths that are not Chinese) is Indian. This means that out of the three-fourths, one-fifth is Indian.
To calculate the percentage of the world's population that is Indian, we multiply the fraction representing the Indian population (1/5) by the fraction representing the remaining population (3/4).
(1/5) x (3/4) = 3/20
Therefore, three-twentieths (3/20) of the world's population is Indian.
To convert this fraction to a percentage, we divide the numerator (3) by the denominator (20) and multiply by 100.
(3/20) x 100 = 15
Thus, 15% of the world's population is Indian.
