143 - 20% = 143 x (1 - (20/100)) = 143 x 0.8 = 114.4
1 x 143, 11 x 13
% rate:= (39/143) x 100%= 0.2727 x 100%= 27.27%
No because 143 doesn't have any other factors other than 143 or 1. ============================================= Another contributor contributed: Yes. 143 = 13 x 11
13 x 2,000 = 26,000 2,000 - 1,989 = 11 13 x 11 = 143 26,000 - 143 = 25,857
1 x 143, 11 x 13 = 143
20320 x 143 = 2,905,760
1 x 143 11 x 13
143 - 20% = 143 x (1 - (20/100)) = 143 x 0.8 = 114.4
143 is not prime - we can see this because it is 1 less than a square. x^2-1 = (x+1)(x-1), and for 143, x=12. Thus, 143=11*13.
Prime factorization:143 = 11 x 13231 = 3 x 7 x 1111 x 13 x 3 x 7 = 3003 (the LCM of 143 and 231).
3 x 143 = 429
13x11=143 Answer:143
1 x 143, 11 x 13.
1 x 143, 11 x 13
11 x 13 = 143
13 x 11 = 143
