Our current Math Unit challenges students with difficult multi-step multiplication of fraction questions. I'd like to point out a support that you could use at home:
Please remember that while some problems do lend themselves to being solved intuitively, and some students do have the habit of solving parts of a problem mentally, we encourage that each step be written out so other students and evaluators can follow a student's work and logic.
We use a method of Read-Draw-Write as a math solution strategy and this is consistent and helpful with Models in Eureka Math and the Zearn practice program on the Internet.
Have a look at this video showing one of the problems for Lesson 16 in the current fractions unit.
(Note: To find this I did a Google video search with these terms:
"Zearn 5th grade math multiplying fractions"
I chose this result: Grade 5 Module 4 Lesson 16"
(and there were other helpful choices in the results as well).
