1. \dfrac{1}{9}=0.11111 - not exact

2. \dfrac{7}{9}=0.77778 - not exact

3. \dfrac{9}{10}=0.90000 - exact

Step-by-step explanation:

If you are referring to the attached picture, then the answers would be the answers above. The first two fractions are not exact because they are repeating decimals (they go on endlessly).

For example, if you divide 1 by 9, you will end up with 0.11111 because each time you subtract 9 from 10, you will get 1 and when you drop a zero, you'll end up with 10 again.

Decimals that are the exact decimal equivalent of a fraction would be one that is non-repeating, like the last one.

Answer from: drakesmith43

1/9 = 0.111111111..., No

7/9 = 0.777777...8, No

9/10 = 0.9, Yes

Dividing by a non-factor of 9 by 9 will always result in an infinite decimal, similar to dividing a non-factor of 3 by 3 or a non-factor of 7 by 7.

However, dividing a number by 10 will simply move the decimal one value to the right, so 9.0 divided by 10 is 0.90.

3.142

1.732

3.464

2.236

Step-by-step explanation:

Value of ∏ in decimal = 3.14159

When rounded to the hundredths is = 3.142

Value of √3  in decimal = 1.732051

When rounded to the hundredths is = 1.732

Value of 2√3  in decimal = 3.4641016

When rounded to the hundredths is = 3.464

Value of √5  in decimal = 2.23606798

When rounded to the hundredths is = 2.236

Answer from: MaeWolfe

a.No

b.No

c.Yes

Step-by-step explanation:

a.We are given that a fraction number

\frac{1}{9}

We have to find that is exact decimal  or not.

Calculator display for \frac{1}{9}=0.11111

It is not an exact decimal equivalent.

\frac{1}{9}=0.11111

A fraction is an exact decimal when the denominator can be expressed as 2^n\cdot 5^m.

9 cannot be expressed as 2^n\cdot 5^m

Hence, \frac{1}{9} is not an exact decimal equivalent.

b.\frac{7}{9}

Calculator display for \frac{7}{9}=0.77778

It is not an exact decimal equivalent because the denominator of given fraction is 9 which can not be expressed as 2^n\cdot 5^m.

Hence, it is not an exact decimal equivalent.

c.\frac{9}{10}

Calculator display for \frac{9}{10}=0.9

10=2\cdot 5

It is an exact decimal equivalent because the denominator 10 can be expressed as 2\cdot 5.

Hence, the given decimal is an exact decimal equivalent.

Calculator display for \frac{9}{12}  = 0.75

calculator display for \frac{5}{12} = 0.41667

Calculator display for \frac{7}{12} = 0.5833

Step-by-step explanation:

Calculator display for \frac{9}{12} is 0.75

Yes , it is the exact decimal equivalent.

\frac{9}{12} = 0.75

9 ÷ 12

=3 ÷ 4

= (3 × 25) ÷( 4 × 25)

         = 75 ÷ 100

         = 0.75

calculator display for \frac{5}{12} = 0.41667

\frac{5}{12} = 0.41667

It is not the exact decimal equivalent.

5 ÷ 12 = (5 × 8.35) ÷ ( 12 × 8.35)

        = 41.75 ÷ 100.2

         = 0.41667

Calculator display for \frac{7}{12} = 0.5833

It is not the exact decimal equivalent.

7 ÷ 12 = ( 7 × 8.35) ÷ ( 12 × 8.35)

          = 58.45 ÷ 100.2

          = 0.5833
