Let's work it out together.
Work through one checkpoint at a time. Your answer area opens after the reasoning.
-
Checkpoint 1
The model divides one whole into 10 equal parts and selects 9 of them.
-
Checkpoint 2
The selected count belongs in the tenths place, one place to the right of the decimal point.
-
Checkpoint 3
Read the decimal as 9 tenths and compare that name with the fraction.
