To solve this, multiply the two numbers together. You can use a calculator or you can do it by hand: 45 X 5 = 225
To convert F to C, subtract 32, then multiply by 5/9 77-32 = 45 45x5/9 = 25 Going the other way, to convert C to F Multiply by 9/5, then add 32
Well, isn't that a happy little math problem! Let's see, if we take 247 and divide it by 45, we find that 45 goes into 247 about 5 times with a remainder of 22. Remember, there are no mistakes in math, just happy little accidents!
436 is the best choice for the next number in the sequence because:3x3=9-5=45x5=25-5=2021x21=441-5=436The Pattern: Square the term, then take away 5, add one, and square it again, and so on.
