El dueño de un colegio prefiere venderlo, para ello debe demostrarla el ingreso que genera dicho colegio cada año. Un comprador le exige que le diga cual ha sido el ingreso promedio del colegio durnte los ultimos ocho años

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870

i think its 7.6

if so your welcome
