The GCF for 80 70 84 is 2.
[80/100]*84 =67.2
100% of the whole = 780 84 : 70% = N : 100% 70%N/70% = (546 * 100%)/70% N = 780
Do you mean 84/100 = 0.84 or do you mean 80/400 = 0.2

I-15,i-70,i-80,i-84.
80, 84, 88, 92, 96, 100
84 / 120 = 0.7 0.7 * 100 = 70%
84 * 78 = 80*70 + 80*8 + 4*70 + 4*8 = 5600 + 640 + 280 + 32 = 6552
* I-15, * I-70, * I-80, * I-84.
alright, you take 70 and multiply it by 1.2, 70 times 1.2 = 84
The median is 84.
