Real problems from these worksheets, solved one step at a time — the same explanations your child sees when practicing online.

1. Example 1

   Zoe walked 1.4 km in the morning and 4.7 km in the afternoon. How many kilometers did Zoe walk in all?

   1. The story puts two amounts together ("in all"), so add.
   2. Line up the decimal points: 1.4 + 4.7. Think in tenths: 14 + 47 = 61 tenths, which is 6.1.
   3. So the answer is 6.1 kilometers.

   Answer: 6.1

2. Example 2

   30.3 − 13.39 = ?

   1. Line up the decimal points of 30.3 and 13.39.
   2. Subtract each column from right to left, regrouping from the next column when needed.
   3. Bring the decimal point straight down into the answer.
   4. 30.3 − 13.39 = 16.91

   Answer: 16.91

3. Example 3

   Rosa ran 2.3 km on Saturday and 1.6 km on Sunday. How many more kilometers did Rosa run on Saturday?

   1. The question compares two amounts ("how many more"), so subtract the smaller from the larger.
   2. Line up the decimal points: 2.3 − 1.6. Think in tenths: 23 − 16 = 7 tenths, which is 0.7.
   3. So the answer is 0.7 kilometers.

   Answer: 0.7
