Question

If one costs £0.05, find the cost of 100

Answer 1

for find the answer we just should multiply 0.05 with 100

so 0.05×100=5 :)

Answer 2

This is quite simple once you understand.
Since 100 is a round number all you must do is move the 0.05 up 2 zeros.
You get the zeros from the hundreds btw.

0.05 x 100 = 5
So the answer is £5
