Answer:
6
Explanation:
Changing the question into an equation format :
20/x = 10/3
Multiply x on both sides :
20 = 10x/3
Multiply both sides by 3 :
60 = 10x
Divide both sides by 10 :
6 = x
x = 6
The number must be 6, but let's check:
20/6
Simplify fraction by finding common multiple:
2
20/6 ÷ 2/2 = 10/3
Same as question so ✅
Hope this helped and have a good day
