[8/9⋅(s⋅9/8)]+h

[( 8/9⋅)⋅s]+h ? Associative Property of Multiplication
[ ? ⋅s]+h Inverse Property of Multiplication
s+h Identity Property of Multiplication

Yes, you are correct. The first step demonstrates the use of the Associative Property of Multiplication, which states that the grouping of factors does not affect the product. The second step shows the Inverse Property of Multiplication, where any number multiplied by its multiplicative inverse (in this case, 8/9) equals 1. Finally, the last step represents the Identity Property of Multiplication, which states that when any number is multiplied by 1, the result is the original number.
