So regrouping
the teacher doesn't want
14 and 0.1
she wants something to take the decimals apart and whole numbers exg
10.2 +3.9=10+0.2+3+0.9=10+3+0.2+0.9=13+1.1=14.1
some examples are
1.2+12.9
2.4+11.7
3.7+10.4
...
Here is your answer in the picture
Answer:
No, you would multiply by 1.15
Step-by-step explanation:
A percentage goes by 'Hundreths' or .01
So 15% would be .15
We don't want to lose money along the way so we add a 1 it so it goes up for the total, like this:
28.75 * 1.15 = 33.1
We are looking for a new number which is 30 less than 10. We will get the new number by subtracting 30 from 10. We write it down as: 10-30=-20
And finally the solution for: What number is 30 less than 10? is -20
Hope this helps!!
