Allison drew a number line to model seven eighths − two eighths. Is the model correct? Explain why or why not. You can write out the fraction names or use the forward slash (/) on your keyboard to represent the fraction bars.
A number line from zero to one partitioned into eighths. There are five hops beginning at seven eighths and ending at two eighths.
no, because the number line shows the arrow going backward, so now we know its subtraction, so you're going to count backward until you reach the number we are looking for so 7/8 minus 2/8 equals 5/8.
