Given 317×45=14265 Consider 3.17×4.5=3.17×100100×4.5×1010[Multiplying 100100 and 1010 for 3.17 and 4.5 respectively]=317×45100×10 =142651000 [Since, given ]=14.265
Express the following decimal expression into rational numbers
3.17
x=3.17
10x=31.7------>1
100x=317.7---->2
Below this I couldn't understand
2-1====>100x-10x=317.7-31.7
90x=286
;. x=286/90=143/45
