Question 1123918
general rules:


percent of new value to old value is equal to new value / old value * 100.


in your problem, the new value is 7 and the old value is 1, therefore the percent of new value to old value is 7 / 1 * 100 = 700%.


percent of new value increase to old value is equal to (new value - old value) / old value.


in your problem, the new value is 7 and the old value is 1.
that's an increase of 6.
the percent increase is 6/1 * 100 = 600%.
