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
A number is divisible by 115 if it is divisible by both 5 and 23, as 115 = 5 * 23. To determine if a number is divisible by 5, you check if its last digit is 0 or 5. To check if a number is divisible by 23, you can use the divisibility rule for 23, which involves subtracting four times the last digit from the rest of the number and checking if the result is divisible by 23.
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
The LCM (Least Common Multiple) of 115 and 15 is 345. The prime factors of 115 are 5 and 23. The prime factors of 15 are 3 and 5. Multiply the smallest encountered number of same factors, 3, 5, and 23, to get 345.
To find 18 percent of a number, multiply the number by 0.18. In this instance, 0.18 x 115 = 20.7. Therefore, 18 percent of 115 is equal to 20.7.
To find 115 percent of a number, multiply the number by 1.15. In this instance, 1.15 x 600 = 690. Therefore, 115 percent of 600 is equal to 690.
