Answer: 350,340,330,320,310,300,290,280,270,260,250,240.
Step-by-step explanation:
To solve this exercise you must keep on mind the following information:
1. By definition skip counting is about counting by a number which is not the number 1.
2. Skip counting by ten from 350 to 240 means that you need to subtract 10 to a number to find the other one.
3. Therefore, you must subtract 10 to 350 and then you need to do this over and over again until you get 240.
43.9 + n = 49.65
43.9-43.9 + n = 49.65 -43.9
n = 5.75
