Simplify 3xy² - 5x²y - 9xy² - 8x²y - 3x²​

-13x^2y - 6xy^2 - 3x^2

Step-by-step explanation:

4/8 and 4/10

Step-by-step explanation:

Required

Select which option is equivalent to 1/2 and 2/5

Option (a): 5/10 and 4/8

Simplify 5/10

Simplify 4/8

This is not true

Option (b): 1/3 and 4/12

1/3 is not equivalent to 1/2 or 2/5.

So, this is not true

Option (c): 4/12 and 5/10

Simplify 4/12

1/3 is not equivalent to 1/2 or 2/5.

So, this is not true

Option (d): 4/8 and 4/10

Simplify 4/8

Simplify 4/10

Hence, (d) is true
