two pairs of numbers equal 100
Chat with our AI personalities
One rule for finding number pairs that add to 100 is to start with one number and subtract it from 100 to find the other number. For example, if one number is 75, subtracting it from 100 gives 25, so the pair is (75, 25).
All of the composite numbers less than 100 have factor pairs.
i don't no so help me aswell An easy way is to take your number, divide by 100 and multiply that answer by 40 Example, what is 40% of 90 90 divided by 100 = 0.9 x 40 = 36
70% of 100 is 70. The way you find this is you divide the percent by 100 (70/100=0.7) then multiply that number (in this case 0.7) by the number you are finding the percent of (in this case 100). So: (70/100)*100
Each number is 0.2 times the previous number.
It is finding an equivalent number whose denominator is 100.
