Order from least to greatest. Start with comparing the tenths place.

Question

3.36, 3.45 and 3.4

smallest number: [?]

Answer 1

To order the numbers 3.36, 3.45, and 3.4 from least to greatest, we start by comparing the tenths place:

• 3.36: tenths place is 3
• 3.45: tenths place is 4
• 3.4: tenths place is 4

Since 3.36 has the smallest tenths place (3), it is the smallest number.

Next, we compare 3.45 and 3.4. Both have the same tenths place (4), but we need to look at the hundredths place now:

• 3.45: hundredths place is 5
• 3.4: has no decimal in the hundredths place, which is considered 0.

Since 0 is less than 5, 3.4 is smaller than 3.45.

Now we can order them:

1. 3.36
2. 3.4
3. 3.45

So the smallest number is 3.36.
