Problem Description:
The image shows a worksheet titled "More and Less," where numbers are placed in a grid. The task involves filling in the missing numbers based on the relationships indicated by the phrases "1 more" and "1 less." Each cell in the grid is labeled with either "1 more" or "1 less," indicating how the number in that cell relates to the number in an adjacent cell.
Step-by-Step Solution:
1.
Identify the Known Numbers:
- Top row: 46, 35, 36, 37
- Second row: 26, 68
- Third row: 4
- Fourth row: 47, 79
2.
Analyze the Relationships:
- "1 more" means the number in the target cell is 1 greater than the number in the reference cell.
- "1 less" means the number in the target cell is 1 less than the number in the reference cell.
3.
Fill in the Missing Numbers:
#### First Row:
- The first row is already complete: 46, 35, 36, 37.
#### Second Row:
- The second row has two known numbers: 26 and 68.
- The relationship between these numbers is not directly given, but we can infer the missing numbers based on the grid structure.
#### Third Row:
- The third row has one known number: 4.
- The relationships are:
- "1 more" from the top-left cell (35).
- "1 less" from the top-right cell (37).
#### Fourth Row:
- The fourth row has two known numbers: 47 and 79.
- The relationships are:
- "1 less" from the top-left cell (26).
- "1 more" from the top-right cell (68).
4.
Solve for Each Missing Cell:
-
Top-Left Cell (Second Row):
- The number above it is 35.
- The relationship is "1 more."
- Therefore, the number is \( 35 + 1 = 36 \).
-
Top-Right Cell (Second Row):
- The number above it is 37.
- The relationship is "1 more."
- Therefore, the number is \( 37 + 1 = 38 \).
-
Bottom-Left Cell (Third Row):
- The number above it is 36.
- The relationship is "1 more."
- Therefore, the number is \( 36 + 1 = 37 \).
-
Bottom-Right Cell (Third Row):
- The number above it is 38.
- The relationship is "1 less."
- Therefore, the number is \( 38 - 1 = 37 \).
-
Bottom-Left Cell (Fourth Row):
- The number above it is 37.
- The relationship is "1 less."
- Therefore, the number is \( 37 - 1 = 36 \).
-
Bottom-Right Cell (Fourth Row):
- The number above it is 37.
- The relationship is "1 more."
- Therefore, the number is \( 37 + 1 = 38 \).
5.
Final Grid:
- Top row: 46, 35, 36, 37
- Second row: 36, 68, 38
- Third row: 37, 4, 37
- Fourth row: 36, 47, 38, 79
Final Answer:
\[
\boxed{
\begin{array}{cccc}
46 & 35 & 36 & 37 \\
36 & 68 & 38 \\
37 & 4 & 37 \\
36 & 47 & 38 & 79 \\
\end{array}
}
\]
