The thousandth place is used when there are three digits right after the decimal point.The hundredth place is used when two digits are right after the decimal point.The tenth place is used by the single digit that comes right after the decimal point. ![]() When we have digits on both sides of a decimal point, we must decompose them by breaking down numbers into parts on both sides. The same principle is applied to large numbers and infinite numbers. When we break the three-digit number, we will decompose it into three pieces: ones, tens and hundreds. In others words, we can say numbers are taken apart.Ī three-digit number with no decimal place, the number on the right side is ones, the number on the left-hand side is hundreds, and the number in the middle is tens. After knowing which digit is at the tens place and which is at one’s place, break down the number into its parts. Then the number on the left side is tens, and the number on the right is ones. Method One: Decomposing Into Hundreds, Tens, and Onesįirstly, we will figure out the concept of ones and tens if we have a two-digit number without any decimal place. There are a couple of methods to decompose numbers, as discussed below. In this figure, 72 and 120 are being decomposed, and their least common factor is 360. If we cut a lemon into two halves, we break a circle into two semi-circles.įigure 3: Illustration of decomposition by the least common factor.If we cut A4 size paper into two halves, we break a rectangular shape into two smaller rectangles.If we cut a pizza, we break a circular shape into triangular shapes.Some real-life examples of decomposing of shapes are as follows We can break it into smaller squares, or we can break it into a triangular form, or it can be a combination of triangles and squares or what so ever. We can break this square into several different types of shapes. The newly formed shape can be wholly different or the same in a smaller size. The decomposition of shape is to break the shape into other smaller shapes. Compose 12 thousands, 3 hundreds, 7 tens, and 3 ones.It is written as 700+80+2, which equals 782. Compose 7 hundreds, 8 tens and, 2 ones.In simple words, the numbers taken apart to write them together are called compose. ![]() As decomposing means breaking numbers into their parts, composing in math means writing numbers together. DecomposingĬompose is the exact opposite of decompose. ![]() Figure 1: Illustration of decomposition by prime factorization Composing vs.
