The number is 72 because (72/9)-7 = 1

Pick any number. Multiply by 6. Add 13. Subtract 7. Divide 3. Divide 2. Then subtract by the original number you chose. Your result will always be 1. Tell a friend to mentaly multiply their age by 2. Tell them to add 14 then divide 2. Ask your friend what number they currently have. Now, you mentally subtract 7 from the number they tell you, then you'll know your friend's age.
Whether the change is an increase or decrease . . . -- Divide the new number by the original number. -- Multiply the result by 100. -- Subtract 100. -- Now you have the percent of change.
You can subtract them or divide them. If you subtract them, the result is their difference. If you divide them, the result is their ratio.
One way:-- Subtract the discount percent number from 100 .-- Multiply the result by the dollar amount.-- Divide the result by 100 .-- The result is the discounted amount.===============================Another way:-- Multiply the dollar amount by the discount percent number.-- Divide the result by 100 .-- Subtract the result from the original dollar amount.-- The result is the discounted amount.

If you add, subtract or multiply rational numbers, the result will be a rational number. It will also be so if you divide by a non-zero rational number. But division by zero is not defined.
The number is 72 because (72/9)-7 = 1
You subtract the smaller number from the larger, then divide the result by the larger number and multiply that result by 100.

Pick a number between 8 and 20. double that number. subtract 16 from that answer. Multiply that result by 4. Divide that total by 8. add 15 to that answer. subtract the number that you started with.
If you divide that by 24, you get the number of days. If you then divide the result by 365, you get the number of years.If you divide that by 24, you get the number of days. If you then divide the result by 365, you get the number of years.If you divide that by 24, you get the number of days. If you then divide the result by 365, you get the number of years.If you divide that by 24, you get the number of days. If you then divide the result by 365, you get the number of years.
Divide your number by 4 and subtract the result from the original number. 149.98 - 149.98 / 4 = 149.98 * .75 = 112.485

The answer to the problem is -40. When you subtract a larger number from a smaller number, the result is a negative number.
