    If you write out the numbers, it'll definitely help. Just type them out or write them on a piece of paper.

    Right! So why did you say that? What makes 437.291 greater than 86.5826?

    When you compared 437.291and 86.5826, how did you tell that 437.291>86.5826?

    Ok, then what makes 437 greater than 81?

  16. Vivi305

    cause there is a 3 digit number and only 2 digit number so that is what make it bigger

    Right! So now that you have that, why is it wrong to say \(87>437\) because \(8>7\)?

    You're so close! you say 437>87 because there's three digits. Sharmi said \(437<87\) because it starts with an 8 and \(8>4\). Sharmi's reasoning is wrong, because he isn't considering the length of the number. How many digits are before the decimal point. This is what you must consider before anything else when deciding some number is greater/less than another number.
