    There is an easier and shorter way, 110% now =286, what about the 100%? Cross multiply 100 by 286 all over 110, the answer is 260 😜

    @@user-wg6rl3br4i Sure, I can help you with that: (a) To increase 200 by 9%, you can calculate it as follows: Increase = 200 x 9/100 = 18 New value = 200 + 18 = 218 (b) To decrease 940 by 13%, you can calculate it as follows: Decrease = 940 x 13/100 = 122.2 New value = 940 - 122.2 = 817.8 (c) To apply a 20% discount to 455, you can calculate it as follows: Discount = 455 x 20/100 = 91 Final price = 455 - 91 = 364
