50% of 6 is 3, so to decrease 6 by 50% you subtract 3 from 6 and you are left with 3.
3/10, 6/20
50% 30/60 = 3/6 = 1/2 = 10/20 = 50/100
3/6 x 100% = 50% Therefore, 3 out of 6 equals 50%.
7*7*2*2*5*3 =(7*7)*(2*3)*(2*5) =49*6*10 =(50-1)*6*10 =(50*6-6)*10 =(300-6)*10 =294*10 =2940
Depending upon where you are: In those countries that use the long scale (based on powers of a million), like Europe: 1 billion = (10^6)^2 = 10^6 × 10^6 = 10^6 million = 1,000,000 million = 1 million million → 50billion = 50 × 10^6 × million = 50,000,000 million = 50 million million In those countries that use the short scale (based on powers of a thousand plus one), like USA: 1 billion = (10^3)^(2+1) = 10^9 = 10^3 × 10^6 = 10^3 million = 1,000 million = 1 thousand million → 50 billion = 50 × 10^3 × million = 50,000 million = 50 thousand million
