250 metres + 9.75 kilometres = 10 kilometres
Yes, since 10-1 = 9
As a number it is 1,200,000,000 kilometers or in scientific notation 1.2*10^9 kilometers
10 + 7 + 0.7 + 0.01 = 17.71
Because the system is based on counting in blocks of ten. A medium large number is represented as a number of thousands (10*10*10) plus a number of hundreds (10*10) plus a number of tens (10) plus some units. Numbers that are larger still would involve ten thousands (10*10*10*10 or 104), or hundred thousands (105), millions (106), etc.
