2/3 x 1 5/8 = kinda struggling with this

You should first turn 1 5/8 into an improper fraction. 1 5/8= 13/8. For fractions, you just multiply regularly.
Let’s do the numerators first (the top number):
2 • 13 = 26
Now the denominators:
3•8= 24
The fraction would be 26/24, but this can be simplified smaller. Let’s divide the top and bottom by two (trick when simplifying is to divide by smaller numbers if you can like 2,3,4).
We now have 13/12, and since 13 is prime, that is the farthest we can simplify to. Let’s make it a mixed number, 1 1/12 is the answer.

Your answer would be B
