First representation:
There are 3 tens of books which are equivalent to each block is 10
There are 5 ones of books which is equivalent to each block is 1
The total books in a cart: 30+5
3*10=30
5*1=5
Therefore, the total marble is 100+40+8.
the total:148
Second representation:
There are 0 ten of books which are equivalent to each block is 10
There are 35 ones of books which is equivalent to each block is 1
The total marbles are 0*10=0
35*1=35
Therefore, the total marble is 0+35
the total:35.

Answer: Place value.
Place value in Maths describes the position or place of a digit in a number. Each digit has a place in a number. When we represent the number in general form the position of each digit will be expanded. Those positions start from a unit place or we also call it one’s position. The order of place value of digits of a number of right to left is units, tens, hundreds, thousands, ten thousand, a hundred thousand, and so on.
We placed digits in different ways in place values.

Question 6.
Multi-Step Minnie has 220 pennies. She already filled these bags. How m more bags of 10 pennies can she fill?
Texas Go Math Grade 2 Lesson 1.7 Answer Key 7
(A) 2 more bags of 10 pennies
(B) 1 more bag of 10 pennies
(C) 3 more bags of 10 pennies
Answer: Option C is correct.
Texas Go Math Grade 2 Lesson 1.7 Answer Key Different Ways to Show Numbers q6
3 more bags of 10 pennies means 3*10=30
Already one hundred bags are given and 9 tens bags are given
1*100=100
9*10=90
Total:100+90=190.
We need to find out the number of more bags needed to get 220 pennies. Assume it as X.
Subtract 220 and 190 then we get the needed bags.
X=220-190
X=30.
Therefore, this can be written as 3 more bags of 10 pennies are needed.
30=3*10.
