solve in reverse 49+15=64 64/8=8 8 is the answer 8*8-15=49
Subtract two, multiply by two, subtract one. :)
To subtract 15 percent from a number, multiply it by (1 - 15/100) = 0.85. Therefore, 162 - 15% = 162 x 0.85 = 137.7.
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.
To subtract 15 percent from a number, multiply it by (1 - 15/100) = 0.85. Therefore, 350 x (1 - 15/100) = 350 - 0.85 = 297.5.
There are two ways - that are essentially the same. Method I: Subtract the percentage from 100. Multiply this number by the original price and divide by 100. Method II: Multiply the original price by the percentage and divide by 100. Subtract the result from the original price. For example, original price = 300, and you want 15% less. Method I: 15% from 100% = 85% 300*85/100 = 255 Method II: 15% of 300 = 300*15/100 = 45 300 - 45 = 255. So, subtract first and then multiply or multiply first and then subtract. The choice is yours.
multiply by 2 then subtract 6
2 and 5 if you multiply them. 50 and 5 if you divide them. 5 and 5 if you add them. 15 and 5 if you subtract them.
First, to subtract fractions, you need to make sure that the both have a common denominator. By this, I mean that they need to have the same number on the bottom of the fraction. If they are not the same, you need to multiply. Say you had this problem: 4/5 - 1/3 You will notice they don't have a common denominator. To make sure that the bottom is the same number, multiply 4/5 by 3 and 1/3 by 5. When you multiply, you do this to both the top and the bottom number. The problem now looks like this: 12/15 - 5/15 Now you're ready to subtract! All you have to do is subtract the top numbers, and keep the bottom ones the same. So: 4/5 - 1/3 = 7/15
4/5 - 4/3 = -8/15To subtract fractions, you simply get a common denominator. To do so find the smallest number that in this case 5 and 3 go into, which would be 15. Then whatever number you need to multiply the denominator to get the lCM (The smallest number that both denominators go into) multiply that by the numberator.So in order to get 5 to become 15 you must multiply by 3, so then you would multiply 4 by 3. Thus the first fraction become 12/15.The same needs to be done with he second. In order to get 3 into 15 you need to multiply by 5. Thus the second fraction become 20/15.Then simply subtract the two numerators.12/15-20/15= -8/15, which becomes your answer
If you take 208.56 and divide it by 100 you can find 1%, which is 2.0856 if you now multiply it by 15 you can find 15%, which is 31.284. Now all you need to do is subtract 31.284 (15%) from 208.56, which gives you 177.276
