Answer:
commutative property
Step-by-step explanation:
The <em>commutative property of multiplication</em> lets you swap the order of the operands (7*3) and 8 to make them have the order 8 and (7*3).
The number will be itself when multiplied by 1.
The sum of twice and half the original number is 1, so the number is
2n +0.5n = 1
2.5n = 1
n = 1/2.5 = 0.4
The original number is 2/5.
