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 =

Write the correct answer:

 8 tenths = 45 units  = 75 tenths = 1,25 units = 475 thousandths = 13 hundredths = 14 units = 27 tenths = 13 thousandths = 7 units =
