New Value =
The original value + Value of Percentage Increase =

1. Calculate the New Value of the number
increased by percentage of its initial value
1 = 100/100 = 100 ÷ 100 = 100%
New Value =
5,000,000,000 + Value of Percentage Increase =
5,000,000,000 + (- 4.2% × 5,000,000,000) =
5,000,000,000 - 4.2% × 5,000,000,000 =
(1 - 4.2%) × 5,000,000,000 =
(100% - 4.2%) × 5,000,000,000 =
95.8% × 5,000,000,000 =
95.8 ÷ 100 × 5,000,000,000 =
95.8 × 5,000,000,000 ÷ 100 =
479,000,000,000 ÷ 100 =
4,790,000,000
2. Calculate the Actual Increase (Absolute Difference)
between the New Value and the initial one
Actual Increase =
New Value - 5,000,000,000 =
4,790,000,000 - 5,000,000,000 =
- 210,000,000
5,000,000,000 increased by - 4.2% percent of the value = 4,790,000,000
The actual increase:
4,790,000,000 - 5,000,000,000 = - 210,000,000
