Answer:
0.7778
Step-by-step explanation:
step 1
Address the input parameters and observe what to be found:
Input values:
The fraction = 21/27
What to be found:
Find the decimal expansion of fraction 21/27.
step 2
The numerator is smaller than the denominator of the fraction 21/27, so find how many 10s should be multiplied with both numerator and denominator. Since the number of digits are equal in both numerator and denominator, multiply 10 with both numerator and denominator of 21/27.

step 5
Repeat the step 2 to find the decimal equivalent for the fraction 21/27 in the above expression:
= (7 + 21
27
) x 1
10
= (7 + 0.778) x1
10
step 6
Simplify the above expression further:
= (7 + 0.778) x1
10
= 7.778 x1
10
=7.778

= 0.7778
Hence,
21/27 as a decimal is 0.7778
Answer:
We can decompose a function into sum of fractions as well.
<em>" Decompose a fraction into a sum of fractions with the same denominator in more than one way, recording each decomposition by an equation " . </em>
<em>Ж</em><em> </em>Now first we will write an expression for \dfrac{3}{8}[/tex]
<em> Ж </em>Now the decomposition of 1 is given as:
And in many more ways we can decompose these numbers.

- Area of shaded region = 2571.66 in²
Radius of smaller circle = 25 in
Radius of larger circle = 25 + 13 = 38 in
Area of ring : Area of larger circle - Area of smaller circle
