Answer:
Ladonna: a + c + b
Step-by-step explanation:
-The commutative property in addition states that the order of arrangement of the integers to be added has no effect on their sum such that:
-Since the alphabet follows the order a,b, c....
Only Ladonna rearranged to change this order to show the commutative property.
-Hence, Ladonna wrote the expression correctly.
*The commutative property should not be confused with the associative property.
-The latter allows you to change the order and terms within the closed parentheses while retaining the answer.
Answer:
5 pieces
Step-by-step explanation:
Given:
Paula's painting has a perimeter of 1.22 meters.
She wants to put ribbon around the edge.
If the ribbon comes in pieces that are 25 centimeters long.
Question asked:
How many pieces of ribbon does she need to go all the way around her painting?
Solution:
Perimeter of painting = 1.22 meters
First of all we will convert it into centimeters:-
As we know:
1 meter = 100 centimeters
1.22 meters = 100 1.22 = 122 centimeters
Now, as given that ribbon comes in pieces of 25 cm long and total we should have 122 cm to go all the way around the painting.
Number of pieces of ribbon will be needed =
Thus, she need 5 pieces of 25 cm long ribbon to go all the way around the painting.
<u>Note</u>:-This is by default understood that few length of 5th ribbon will be left over.
