1. Convert decimals to percentages:

a) 0.543 can be converted to percentage by multiplying it by 100. So, 0.543 x 100 = 54.3%

b) 0.0098 can be converted to percentage by multiplying it by 100. So, 0.0098 x 100 = 0.98%

c) 1.67 can be converted to percentage by multiplying it by 100. So, 1.67 x 100 = 167%

2. Convert percentages to decimals:

a) 10% can be converted to a decimal by moving the decimal two places to the left. So, 10% = 0.10

b) 0.010% can be converted to a decimal by moving the decimal four places to the left. So, 0.010% = 0.0001

3. Convert mixed numbers to fractions and decimals:

a) 2 1/3 can be converted to a fraction by finding a common denominator of 3 and writing the whole number as a fraction. So, 2 1/3 = (2 x 3 + 1) / 3 = 7/3

It can also be converted to a decimal by dividing the numerator by the denominator. So, 7/3 = 2.333...

c) 5 3/5 can be converted to a fraction by finding a common denominator of 5 and writing the whole number as a fraction. So, 5 3/5 = (5 x 5 + 3) / 5 = 28/5

It can also be converted to a decimal by dividing the numerator by the denominator. So, 28/5 = 5.6

4. Convert fractions to mixed numbers:

a) 11/4 can be converted to a mixed number by dividing the numerator by the denominator and writing the remainder as a fraction. So, 11/4 = 2 3/4

b) 16/7 can be converted to a mixed number by dividing the numerator by the denominator and writing the remainder as a fraction. So, 16/7 = 2 2/7

a) 10%= 10÷100= 0.1

b) 0.010%= 0.010÷100= 0.0001

To convert mixed numbers into decimals, convert mixed numbers into improper fractions and divide

3)

a)2 1/3= 7/3= 2.333 =233.3%

b)5 3/5= 28/5= 5.6 =560%

To convert a fraction into a mixed number, divide the numerator by the denominator
