26 + 78 + 25 + 75 = 204
53 + 25 = 78
A reasonable estimate of the sum of 78 and 119 is 197.
The answer to this problem is 75.
(75+83+78+X)/4=80, solve for X X=4*80-75-83-78 So X=84
26 + 78 + 25 + 75 = 204
78% of 25= 78% * 25= 0.78 * 25= 19.5
it is 78 because 5x5=25+50=75+3
3945 * 78 = approx 4000*75 = 4000*(3/4*100) = (4000*3/4)*100 = 3000*100 = 300,000
83
There might be more, but the numbers 5, 15, and 75 all do that.
78/25 = 3 3/25
53
Over 96 percent 75/78 x 100 = 96.15384615384615
