Question

2.the decimal expansion is 123/250
is non-terminating recurring
3. The decimal expansion of
The graph of 5y + 7 = 0 is a line parallel to the y-axis. 3​

Answer 1

Answer:

2. Terminating

Step-by-step explanation:

123/250 can be written as 123/2^1×5^3.

123/250 can be written as 123/2^1×5^3.if the denominator of a no. is in the form of 2^m×2^n then the fraction is terminating.

Answer 2

Answer:

(2) it is terminating

Step-by-step explanation:                                          

=   $\frac{123}{250\\}$

=   $\frac{123}{2^{1}*5^{3} }$

multiplying numerator and denometre by $2^{2}$

= 123 * 2^2

  2^1  * 5^3 *2^2

= 123 * 4

  $2^{3\\}$ *$5^{3}$

if the denometer of no. is in the form of $2^{n\\}$ and $5^{n}$ then the fraction is terminating.
