Answer:
ab² - a²b
Step-by-step explanation:
a²b⁴ - b²a⁴ can be factored as a²b²(b² - a²) which becomes a²b²(b + a)(b - a). Since the numerator and denominator both have (a + b) and ab the final answer is ab(b - a) = ab² - a²b.
Answer:
Ratios are usually proportional if they are the same or have the same relationship.
Step-by-step explanation:
Like: you have 2 fractions that reduce and come out the same they are proportional.
Hope my answer has helped you!
Step-by-step explanation:
Remember that 6/6 = 1, so we can use that knowledge to our advantage.
1/2 + 1/2 is one of them, because 1/2 + 1/2 = 2/2 = 1.
1/4 + 1/4 + 1/4 + 1/4 is one of them, because they equal 4/4 = 1.
1/3 + 1/3 + 1/3 is one of them, because they equal 3/3 = 1.
