5 tenths, how many hundredths are? Every tenth has 10 hundredths, then 5 tenths will have 50 hundredths
7 tenths = 

12 tenths = 

324 tenths = 
We can go from tenths to hundredths, multiplying the tenths by 10. Integers are multiplied by 10, placing a 0 on the right.
Write the correct answer:
7 x 10 = 

18 x 10 = 

375 x 10 = 
Decimal numbers are multiplied by 10 moving the comma one place to the right. Example: 3.2 x 10 = 32
5,4 x 10 = 

19,7 x 10 = 

8,45 x 10 = 

18,375 x 10 = 

5,7 x 10 = 
When a decimal number has zeros after the comma, at the end of the number, we can delete those zeros since they have no value.
Write the correct answer:
3,140 = 

2,200 = 

437,850 = 
In order to convert the tenths to thousandths, we multiply the tenths by 100, moving the decimal comma two places to the right. Example: 7.257 tenths = 725.7 thousandths.
Write the correct answer:
3,2 Tenths = 

3,75 Tenths = 

14,789 Tenths = 
In order to convert the units to thousandths, we multiply the tenths by 1000, moving the decimal comma three places to the right. Example: 5.25 units = 5250 thousandths.
Write the correct answer:
6 units = 

3,7 units = 

14,75 units = 
In order to convert hundredths to tenths we have to do groups of 10 hundredths to do a tenth. With 30 hundredths we have 3 tenths. What we have done is to divide by 10. For this we move the comma one place to the left. Example: 50 hundredths = 5 tenths.
Write the correct answer:
70 hundredths = 

130 hundredths = 

1200 hundredths= 
In order to convert hundredths to units we have to make groups of 100, move the decimal comma two places to the left. Example: 700 hundredths = 7 units.
Write the correct answer:
3750 hundredths = 

457 hundredths = 

56,5 hundredths= 
We convert the thousandths to units dividing by 1000, moving the decimal comma three places to the left. Example: 327 thousandths = 0.327 units.
Write the correct answer:
2525 thousandths = 

5 thousandths = 

25 thousandths =
