decorated 5/9 pages in her book. Diana decorated 5/6 of the pages in her book.
Use a tape diagram to show who has decorated more pages of their scrapbooks.
Draw 2 number lines. And label the endpoints 0 and 1.
Partition the first number line into eighths and the second one into tenths.
On the first number line, make an arrow to label 8/8 of the unit fraction. On the second number line, make an arrow to label 2 copies of 5/10
Give a sentence comparing the fractions using the words ‘greater than,’‘less than,’ or ‘equal to.’ They are equal because they have the same point on the number line. That means they’re equivalent.
Now write the comparison as a number sentence with the correct symbol between the fractions.
