Step-by-step explanation:
Work out the area of each section then add them all together.
addition (+) expression the students used to find the answer.
Solution:
Given data: A student is asked to find the sum of 197 and 413.
Sum means adding two numbers or variables.
For addition, we use + symbol to add two numbers.
First add last digit of the numbers (7+3) = 10.
Put 0 in last and carry 1 to the next left digit top.
Add middle digits with carry over 1 (1 + 9 + 1) = 11
Put 1 and carry another 1 to the next left digit top.
Add first digit of the numbers with carry over 1 (1 + 1 + 4) = 6
Sum of 197 + 413 = 197 + 413
= 610
The addition image attached below.
Hence, addition (+) expression the students used to find the answer.
15 x 100 / 80 = 18.75
To hmthe nearest tenth is 18.8
The total lengths are equal. 1/4 plus 1/4, or 0.25 plus 0.25, equals 0.5, or 1/2 so thus they are equal.
