Ответ:
B
Step-by-step explanation:
Both of the two numbers should equal the same amount when dividing.
For example, in A
25÷15=1.666...
30÷18=1.666...
Both of these answers are the same so that means that 25/30 is equivalent to 15/18
When you're dividing B though, they don't equal the same amount
90÷15=6
105÷18= 5.833...
that means that 90/105 does NOT equal 15/18
good luck
