How can this model be used to determine 2.4−0.15 ?

Enter your answers in the boxes.

The model shows a total of 2 wholes and 4 tenths. After regrouping 1 tenth into 10 hundredths, there are 2 wholes,
tenths, and [box]
hundredths. After crossing out 1 tenth and 5 hundredths, there are 2 wholes, [box]
tenths, and [box]
hundredths remaining. Therefore, the difference of 2.4 and 0.15 is [box]
. (25 points to the person who helps me with this question)
