Answer:
145, 29, 2.9
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.
2.9
