The first part is 15% and the second part (which is what is cost) is 85%. You would multiply 115/1 x 85/100 or 17/20 which equals 1955/20. Now, divide. 97R15. 97 dollars and 15/20 of a dollar. 20 is a factor of 100 by 5, so multiply 15 by 5. It is in the cents place. The total is $97.75.
The first ten positive integer multiples of 115 are as follows: 115 x 1 = 115 115 x 2 = 230 115 x 3 = 345 115 x 4 = 460 115 x 5 = 575 115 x 6 = 690 115 x 7 = 805 115 x 8 = 920 115 x 9 = 1035 115 x 10 = 1150
23 x 5=115
15
x/5 = 3 Multiply both sides by '5' x = 15
1 x 115, 5 x 23, 23 x 5, 115 x 1
15% off 115 pounds = 115 pounds - (0.15 x 115 pounds) = 97.75 pounds
15% off 115 pounds = 115 pounds - (0.15 x 115 pounds) = 97.75 pounds
To find out what whole numbers can be divided by 115, first find the multiples. 115 x 2 = 230 115 x 3 = 345 115 x 4 = 460 etc.. All the results are multiples of 115. In this case 230, 345, and 460 are all divisible by 115.
The first part is 15% and the second part (which is what is cost) is 85%. You would multiply 115/1 x 85/100 or 17/20 which equals 1955/20. Now, divide. 97R15. 97 dollars and 15/20 of a dollar. 20 is a factor of 100 by 5, so multiply 15 by 5. It is in the cents place. The total is $97.75.
Any number can multiply 115.
To simplify matters. ex... 15 x 23 since 15 is 3 x 5 we can sub. 15 x 23 = (3x5) x 23 = (3) x (5 x 23) = 3 x 115 easier to multiply by 5 than 15 = 345 There are more reasons in advanced math classes, Trig and Calculus
You change the percent to decimal form, then multiply. For example, if you want to multiply 75 x 15% you multiply 75 x .15, which = 11.25
1 x 15, 3 x 5
