What is percent ?
In mathematics, a percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by whole and multiply by 100.
Hence, the percentage means, a part per hundred. The word per cent means per 100. It represented by the symbol “%”
Problem 1 :
135%
Solution :
= 135%
= 135 ÷ 100
Since we have two zeroes at the denominator, we move the decimal two digits backward.
135% = 1.35
Problem 2 :
18.4%
Solution :
= 18.4%
= 18.4 ÷ 100
Since we have two zeroes at the denominator, we move the decimal two digits forward.
= 0.184
Problem 3 :
42.5%
Solution :
= 42.5%
= 42.5 ÷ 100
Since we have two zeroes at the denominator, we move the decimal two digits forward.
= 0.425
Problem 4 :
37.5%
Solution :
= 37.5%
= 37.5 ÷ 100
Since we have two zeroes at the denominator, we move the decimal two digits forward.
= 0.375
Problem 5 :
46.4%
Solution :
= 46.4%
= 46.4 ÷ 100
Since we have two zeroes at the denominator, we move the decimal two digits forward.
= 0.464
Problem 6 :
9 1/2%
Solution :
= 9 1/2%
Mixed fractions is convert to the improper fractions.
= 19/2%
= 9.5 ÷ 100
Since we have two zeroes at the denominator, we move the decimal one digits forward.
= 0.095
Problem 7 :
6 2/3%
Solution :
= 6 2/3%
Mixed fractions is convert to the improper fractions.
= 20/3%
= 6.7 ÷ 100
Since we have two zeroes at the denominator, we move the decimal one digits forward.
= 0.067
Problem 8 :
8 1/2%
Solution :
= 8 1/2%
Mixed fractions is convert to the improper fractions.
= 17/2%
= 8.5 ÷ 100
Since we have two zeroes at the denominator, we move the decimal one digits forward.
= 0.085
Problem 9 :
7.8%
Solution :
= 7.8%
= 7.8 ÷ 100
Since we have two zeroes at the denominator, we move the decimal one digits forward.
= 0.078
Problem 10 :
21.4%
Solution :
= 21.4%
= 21.4 ÷ 100
Since we have two zeroes at the denominator, we move the decimal two digits forward.
= 0.214
