1. Subtracting tenths. I am learning to subtract with 1 decimal place fractions. Questions like 3.7 - 2.9 = ?

2. Anita had 2.6 of a chocolate bar left after her party. She then ate another 0.9 How much does she have left? Step 1: Imagine the 2.6 chocolate Step 2: We can’t take 0.9 away because we only have 0.6 To fix this we will have to remove one of the whole chocolate bars from its wrapper so we can subtract 9. 2.6 – 0.9 Step 4: Now we can remove the 9 tenths. 2.6 – 0.9 = 1.7

3. Andre had 3.2 of a chocolate bar left after Christmas. He then ate another 1.6 How much does he have left? Step 1: Imagine the 3.2 chocolate Step 2: We can subtract the whole so let’s do this now. 3.2 – 1.6 Step 4: Now we can remove the 6 tenths. 3.2 – 1.6 = 1.6 chocolate Step 3: We can’t take 0.6 away because we only have 0.2 To fix this we will have to remove one of the whole chocolate bars from its wrapper so we can subtract 0.6
