Question

1.15 x 0.85 bata do with formula​

Answer 1

Step-by-step explanation:

To increase a number by a percentage I was taught the formula no x 1.percentage, so for example:

100 increased by 15%:

100 x 1.15 = 115

But today, I learned the hard way that doing the inverse of the above (i.e. no / 1.percentage), isn't the correct way of decreasing a number by a percentage (aka "applying a discount"). E.g:

100 decreased by 15%:

100 / 1.15 = 86.95652 <- WRONG

100 - (100 x 0.15) = 85 <- RIGHT

Answer 2

Answer:

0.9775
