Which change would make the statement below true? 3.9=39

a change 3.9 to 3.90

b change hundredth to tenths

c change hundredth to ones

d change 3.9 to 390

B) change in hundredths to tenths

Step-by-step explanation:

We are given the following information in the question:

A number 3.9 is transformed to 39. We need to explain this transformation.

First we make the place value chart for the given numbers:

Place value:      Tens     Ones  .  Tenths      Hundredths

             3.9:                       3     .       9                     0

          39.0:            3         9     .       0

The transformation that takes place is the zero in 3.90 is changed from the hundredths position to the tenths position.

This is done by multiplying 3.90 and 10. This can be shown as:

Hence, the translation is given by the option B) change in hundredths to tenths
