In this lesson you’ll learn to solve equations with decimals by multiplying by powers of 10. We can solve an equation with decimals by multiplying the equation by a power of 10, and that’s the first thing we’ll do in order to get rid of the decimals by changing them to whole numbers.
Read MoreIn this lesson, we’ll learn how to convert between fractions, decimals, and percents. We can always use a proportion to help us convert between fractions, decimals, and percents. We’ll follow a very specific rule for each conversion, so we’ll look at the conversion between fractions and decimals, fractions and percents, and decimals and percents.
Read MoreWe can add, subtract, multiply, and divide decimal numbers. Addition and subtraction of decimal numbers works the same way as whole number addition and subtraction; we just need to make sure that we line up the decimal points.
Read MoreThere are two kinds of decimal numbers that go on forever and ever. Some decimals that go on forever eventually get to a point where a certain digit (or sequence of digits) repeats infinitely, but some decimal number that go on forever don’t repeat. We’ll look here at how to simplify repeating decimal numbers.
Read MoreWhen we’re dealing with decimal numbers, rounding is an important tool that we need to know how to use. When we round, we always round to a certain decimal place.
