Use a series to express the following number as a ratio of integers: 0.73737373

The number is 0.7373, and notice it is a repeating decimal. The solution is as follows:

Let x = 0.737373  eqn. 1

100x =73.737 eqn. 2

Subtracting the eqn 1 from eqn 2

99x = 73

x = 73/99

therefore the number could be expressed as 73/99

 

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
