What is the fraction of 0.72 repeating

8/11

Step-by-step explanation:

There is a trick in dealing with 0.727272727272 to make it into a fraction.

x = 0.727272727272           Multiply by 100

100x = 72.727272727272...     Now write x below it

     x =   0.727272727272        Subtract

99x = 72                                    The repeating decimal is gone ÷ 99

99x/99 = 72/99                         Reduce

x = 72 / 99 = 8/11

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
