Answer:

145, 29, 2.9

Step-by-step explanation:

To convert 14.5 into tenths, first split the number apart.

0.5 is another way of saying one half or 1/2 which is also 5/10.

14 is the same as saying 14/1.  If you want tenths, add a zero to the bottom and top which gives you 140/10

So put back together, you have 145/10 or 145 tenths.

The second question is to divided 145/10 by 5.

When you divide a fraction by a whole number you first have to change the whole number into a fraction.

145                       5

-----  divided by  -----

10                          1

When you divided fractions, you flip the fraction that you are dividing by which was the 5.  Then you multiply the new fractions.  Now you would have:

145         1         145

-----  X  -----  =  -------

10          5          50

Convert this into tenths by dividing the top and bottom by 5.

145      145/5        29

-----  =  ---------  =  -------

50       50/5          10

The last question is to convert the above fraction back into a non-fraction.

Divide the top and bottom by 10.
