Write these numbers in order, starting with the smallest. 0.78, 0.607, 5.6, 0.098, and 4.003.
The question tells us to write the numbers in order, starting with the smallest. To find the smallest number, let’s start by looking at the ones digit. Each of these three numbers have a zero in the ones place. To compare each of these numbers, we need to move to the next column to the right and compare the tenths digit. 0.78 has seven tenths. 0.607 has six tenths. And 0.098 has no tenths. So this is the smallest number.
Now, we can cross this number out and compare the other four to find the next smallest. We already know that 0.78 has seven tenths and 0.607 only has six tenths. Six is less than seven. So the next number in our sequence is 0.607. Now, we just need to compare 0.78, 5.6, and 4.003 to find the next smallest number.
0.78 is the smallest because it has no ones. And the others have five ones and four ones. Which of our two remaining numbers is the smallest, 5.6 and 4.003? 4.003 only has four ones which means that 5.6 is the largest number. These numbers, in order, starting with the smallest are: 0.098, 0.607, 0.78, 4.003 and 5.6. We found our answer by comparing the value of each number. Then we ordered the numbers from smallest to largest.
