Answer:
We know the 80% is x and we know 2/7 of x = 640.
640=2/7x
640/2=320 so 320 is 1/7
if we multiply 320 x 7, it’s a whole fraction now
= 2240
so 2240 is 80% of a number
now let’s convert percentages to fractions
80% = 4/5
2240/4= 560
if 560 is 1/5 then five times that is 2800
We now have the whole number
time to find 120%
100% + 20%
100% = 2800
2800/5=560=20%
so 2800+560=3360
Thus, the number is 3360
