Question

A.Convert 7/9 to a percent and decimal.b.Write these numbers from least to greatest: 6/8, 7/8, 7/9

Answer 1

a. To convert the number 7/9 to a decimal we need to solve the division:

`(7)/(9)=0.778`

Thus, 7/9 as a decimal number is 0.778.

To convert it to a percent, multiply the decimal form by 100%:

`0.778\cdot100=77.8\text{ \%}`

b. To write the numbers from least to greatest we need to convert these fractions to the same denominator, we can do it by multiplying the fractions 6/8 and 7/8 by 9/9 and the fraction 7/9 by 8/8, as follows:

`\begin{gathered} (6)/(8)\cdot(9)/(9)=(54)/(72) \\ (7)/(8)\cdot(9)/(9)=(63)/(72) \\ (7)/(9)\cdot(8)/(8)=(56)/(72) \end{gathered}`

Thus, in order from least to greatest it is: 54/72 , 56/72 , 63/72.

This order corresponds to:

6/8 , 7/9 , 7/8
