Mixed Number Percent

Introduction to mixed number percentage:

Numbers are the basic blocks of mathematics. Numbers are of different types, they are natural numbers, whole numbers, rational numbers, irrational numbers, mixed numbers, fraction numbers, decimal numbers etc.  Mixed number percentage is defined as converting a mixed fraction into percentage, for this the first step is to convert the mixed number into improper fraction, then  the improper fraction is converted into a decimal value and multiplied by  a value of hundred.

Problems for Mixed Number Percentage:

Problem 1:

Find mixed number percentage of 4 ½.

Sol:

Step 1: convert mixed number to improper fraction,

Step 2: then improper fraction to decimal value and then multiply by hundred,


4 1/2 = ((4*2) +1)/2 = 9/2 = 4.5

Multiply 100 with this to get the percent,

4.5 X 100 = 450%

So the result is 450%

Problem 2:

Find mixed number percent of 6 ½.

Sol:

Step 1: convert mixed number to improper fraction,

Step 2: then improper fraction to decimal value and then multiply by hundred,


6 1/2 =((6 X 2)+1)/2 = 13/2 = 6.5

Multiply 100 with this to get the percent,

6.5 X 100 = 650%

so the result is 650%

Problem 3:

Find mixed number percent of 8 ½.

Sol:

Step 1: convert mixed number to improper fraction,

Step 2: then convert  improper fraction to decimal value and then multiply by hundred,


8 1/2 = ((8 X 2) +1)/2 = 17/2 =8.5

Multiply 100 with this to get the percent,

8.5 X 100 = 850%

so the result is 850%

More Problems for Mixed Number Percentage:

Problem for mixed number percentage to fraction form:

Ex 1:

Find mixed number percentage of 8 ½.

Sol:

Step 1: convert mixed number to improper fraction,

Step 2: then improper fraction value divides by hundred,


8 1/2 = ((8 X 2) +1)/2 = 17/2 %

Multiply 100 with this to get the percent,

(17/2) * 100)

so the result is 850%

Ex 2:

Find mixed number percentage to fraction:

=7 ½ (mixed number)

Sol:

Step 1: convert mixed number to improper fraction,

Step 2: then improper fraction value divides by hundred,


7 1/2 = ((7 X 2) +1)/2 = 15/2 %

Multiply 100 with this to get the percent,

(15/2) X 100

so the result is 750%
