Walt: Add and subtract decimals in tenths and hundredths
Walt: Solve decimal word problems . 


Subtracting Decimals  1
Subtract the decimals and whole numbers to answer the questions below. Remember to show your working you can do this by writing it in the document or inserting a photo.


Question
Working and answer
0.7 - 0.5= 0 . 2
0 . 2 so the working out is 0 . 7 - 0 . 5 = 0 . 2 so the answer is 0 . 2
0.4 - 0.1= 0 . 3
0 . 3 so the working out is 0 . 4 + 0 . 1 = 0 . 3   so the answer is 0 . 3
0.9 - 0.3= 0 . 6
0 . 6 so the working out is 0 . 9 + 0 . 3 = 0 . 6   so the answer is 0 .  6
0.6 - 0.3= 0 . 3
0 . 3 so the working out is 0 . 6 + 0 . 3 = 0 . 3 just like 6 - 3 = 3  so the answer is 0 .  3
0.7 - 0.2= 0 . 5
7 - 2 = 5 but in Decimals its 0 . 7 + 0 .  2 = 0 .  5 so the answer is 0 .  5
0.8 - 0.4 =0 . 4
8 - 4 = 4 but Decimals its 0 . 8 + 0 . 4 = 0 . 4 so the answer is 0 . 4
2.6 - 1.3= 1 . 3
2 - 1 = 1 right so then 0 . 6 - 0 . 3 = 0 . 3 so then add it all up and it makes 1 . 3
9.8 - 1.5= 8 . 3
9 - 1 = 8 right so then 0 .  8 - 0 . 5 = 0 . 3 then add it up up = 8 .  3                 
9.4 - 3.2= 6 . 2
9 -  3 = 6 so then  0 . 4 - 0  . 2 = 0 . 2 so then add up 6 + 0 . 2 = 6 . 2
6.8 - 5.1= 1 . 7
6 - 5 = 1 so then 0 . 8 - 0 . 1 = 0 . 7 add it all up = 1 . 7
8.3 - 5.2=
3.1 - 8.3 - 5.0 = 3.3 - 3.3 - 0.2 = 3.1
9.6 - 5.4=
4.2 - 9.6 - 5.0 = 4.6 - 4.6 - 0.4 = 4.2
8.7 - 3.7=
5.0 - 8.7 - 3.0 = 5.7 - 5.7 - 0.7 = 5.0
4.2 - 2.2=
4 - 2 = 2 so then 0 . 2 - 0 . 2 = 0 . 0 so then add it all up = 4 whole


In these question you have to subtract from the whole.
Question
Working and answer
5.5 - 0.6
4 . 9
4.7 - 0.8
3 . 9
1.5 -0.6
0 . 9
2.2 - 0.4
1 . 8
1.7 - 0.9
0 . 8
