Answer:

2.25

Step-by-step explanation:

2.4 - 0.15

Using place value :

2 = Unit (2 wholes)

4 = tenth place ( 4 tenths)

To subtract 0.15

0 wholes ; 1 tenth ; 5 hundredth

1 tenth can be split into 10 separate hundredths

Hence,

For 2.4

We have ;

2 wholes ; 3 tenths and 10 hundredths

Subtracting 0.15 ;0 wholes ; 1 tenth ; 5 hundredth

(2 - 0) wholes = 2 whole

(3 - 1) tenth = 2 tenth

(10 - 5) hundredth = 5 hundredth

Hence, the difference between (2.4 and 0.15) is :

2 whole ; 2 tenth ; 5 hundredth

Which is equal to : 2.25
