Step-by-step explanation:
Given expression :
Step 1: = -4 3/7+(-3 4/7) + 7
Step 2: = -4 + (-3/7) + (-3) + (-4/7) + 7
Step 3: = -4 + (-3/7) + (-4/7) + (-3) + 7
Step 4: = -4 + (-1) + (-3) + 7
Step 5: = -8 + 7
Step 6: = -1
In 3rd step they just swap the positions of (-4/7) and (-3) to bring the like fractions with common denominator together.
Swapping the numbers is the Commutative Property of Addition.
Therefore, correct option is B) The commutative property of addition.Ответ:
