Answer: The required fraction forms of the given decimals are
i) 0.555... =
.
ii) y =
.
Step-by-step-explanation: We are given to express the following decimals in the form of
.
, where p and q are integers and q is not equal to 0.
i)0.5555........
ii)0.5777
The conversions of the given decimals to fraction forms are as follows :
(i) let 0.5555... = x.
then, we have
x=0.555...
10x=5.555...
10x=5+0.555...
10x=5+x 10x-
x=5
9x=5 x={5}
{9}.
So, 0.555...={5}{9}
(ii) let 0.5777...=y.
then, we have
y=0.5777...
100
100y=57.777...
100y=57.2+0.5777...
100y=57.2+y
y=57.2
99y=57.2
y={57.2}{99}
y={572}{99}
y={286}
{495}
So, y={286}{495}
Thus, we the required fraction forms of the given decimals are
(i)0.5555...={5}{9}
(ii)0.5777...={286}{495}
