Question

HELP PLEASE I NEED THIS DONE ASAP

Answer 1

a). 0.45 with a line over the 45 means 0.45454545454545... forever.

It's equivalent to  45/99  which is  5/11 .

b). 0.45 with a line over the 5 means 0.455555555... forever.

It's equivalent to (0.4 + 0.555555.../10)

The 0.4 part is  4/10

The 0.5555555555.../10 part is  5/90 .

(4/10) + (5/90) = 41/90

c). 0.45 means 45/100 .  That's 9/20 .
