Answer:
3 small cups
Step-by-step explanation:
The correct answer would be 3 small cups.
The big cup can hold 9/10 of the total seeds.
The small cup can hold 3/10 of the total seeds.
3 of the small cup would be equivalent to the big cup such that:
3 x 3/10 = 9/10
Hence, 3 small cups = 1 bigger cup.
