0.5 =
0.65 =
0.22 =
0.2 =
0.225 =

6. You have to simplify / reduce the fraction if possible
Is that all there is?
Of Course Not
You have to simplify / reduce the fraction if possible

7. Write .6 as a fraction

.75

10. One more thing………
When you divide, REMEMBER, add zeros to finish your division.
AND
2 THINGS CAN HAPPEN

11. The division problem ends
A Terminating decimal
The division problem goes on forever….Repeating decimal

12. Repeating Decimals A single digit might repeat…. .3333….
Or a group of digits might repeat… ….

13. Show repeating decimals by placing a line over the digit or group of digits that repeats
.33333…. Becomes .3
And
….becomes .275
