This is one of the strategies suggested in the Common Core State Standards for Mathematics. With practice, this strategy can theoretically help younger students gain fluency when subtracting within 20.
I am not a math theorist, so it's mystifying to me how adding an extra step that one is supposed to forget later when the process is memorized could be helpful.
17 - 8 = 17 - 7 - 1 = 10 - 1 = 9

178
It is: 178/9 times 9 = 178 or 19 and 7/9 times 9 = 178
ten centimeters make a decimeter
There are 167 numbers between 10 and 178. There are, therefore 2167 = 1.87*1050 sets.
180
Note, there are 14 pounds (lb) is 1 stone.Therefore, (14 × 12) + 10 = 178 pounds (lb).
178+
94-56=
15% of 178 = 15% * 178 = 0.15 * 178 = 26.7
30% of 178= 30% * 178= 0.3 * 178= 53.4
They are: 2*89 = 178 and 1*178 = 178
It means to make some thing smaller by ten times.
results for cholesterol 209, ldl 129, hdl 44, triglycerides 178
Half of 178 is 178/2 = 89
178 percent of 600 = 1068 178% of 600 = 178% * 600 = 178%/100% * 600 = 1.78 * 600 = 1068
The average is all the numbers added together and divided by how many numbers there are. In this case: 78+100=178. 178/2=89. Therefore the mean/average of the two numbers is 89.
