Explanation:
In the above-given question,
given that,
there are bundles of hundreds, tens, and ones.
there are 2 hundred.
2 x 100 = 200.
2 hundreds = 200.
1 ten = 1 x 10.
1 x 10 = 10.
1 one = 1.
1 x 1 = 1.
200 + 10 + 1.
210 + 1 = 211.
Answer:

177, 178, 179, 180, 190, 200, 210, 211, 212, 213, 214
Answer:
Sally counted 10 for each number.
Explanation:
In the above-given question,
given that,
Sally did some counting.
the first sally takes one number.
the number is 177.
she adds 1 for the next four numbers.
177 + 1 = 178.
178 + 1 = 179.
179 + 1 = 180.
then she adds 10 for the next 4 numbers.
180 + 10 = 190.
190 + 10 = 200.
200 + 10 = 210.
then again she adds 1 for the next 4 numbers.
210 + 1 = 211.
211 + 1 = 212.
212 + 1 = 213.
213 + 1 = 214.
Question 4.
Show a way to count from 68 to 130 using tens and ones. Explain why you chose to count this way.
Answer:
I counted 10 for each number.
Explanation:
In the above-given question,
given that,
I did some counting.
first I takes one number.
the number is 68.
she adds 1 for the next four numbers.
68 + 1 = 69.
69 + 1 = 70.
70 + 1 = 71.
71 + 1 = 72.
then she adds 10 for the next 4 numbers.
72 + 10 = 82.
82 + 10 = 92.
92 + 10 = 102.
102 + 10 = 112.
112 + 10 = 122.
then again she adds 2 for the next 4 numbers.
122 + 2 =124.
124 + 2 = 126.
126 + 2 = 128.
128 + 2 = 130.
