In order to simplify the resolution process, we begin by breaking down the number 354 into a smaller addition exercise.
It is easier to choose round whole numbers, and also to consider numbers that are easily divisible by 3.
Hence the following calculation:
Once again, for the purpose of facilitating the resolution process, we break down 54 into a smaller addition exercise.
Just as in the previous calculation we choose round numbers and numbers divisible by 3.
We obtain the following:
We then divide each of the terms within the parentheses by 3:
We finish by adding up all the results we obtained:
118
\( 140-70= \)
Breaking large numbers into smaller, manageable chunks makes division easier! It's like eating a big sandwich - you take smaller bites instead of trying to eat it all at once.
Choose numbers that are easy to divide by 3! Numbers like 300, 30, and 24 work great because they're multiples of 3. This makes the mental math much simpler.
That works too! and . But using multiples of 3 like 300 + 54 keeps the math cleaner with whole number results.
Use multiplication to check division! Take your answer (118) and multiply by the divisor (3). If you get the original number (354), you're correct!
Yes! You can use long division algorithm, but breaking apart helps you understand what's happening in each step. Both methods give the same answer!
You'll get a remainder! For example, 355 ÷ 3 = 118 remainder 1, which can also be written as .
