Decimal Terms Decimals don’t complicate anything but they make things messy. However, there are tricks to make the calculations easier. Example Any ideas how we can make this simpler? Solve ×10 ×10 4 Let’s multiply it all by 10! -5 -5 - Makes it easier, yeah?
Decimal Terms Multiply the decimal by 10, 100, 1000 or whatever that’ll make the numbers integers. Example Solve As the smallest term has a coefficient in the hundredths, let’s multiply by 100. Big numbers make things messy! Try the worksheet!
Fractional Terms Example Are fractions nice and easy? Let’s see! Solve Hahaha, that was a bit of a bargain…let’s try a harder one.
Please try the last worksheet! Fractional Terms Example is another way to write . is another way to write . Solve Oh dear! What is ?? We need to find a common denominator. If we run out of room vertically, we can use (implies that).
