Why is a divided by B equal to a of B?

This is the definition of score. What do you want to say?
In addition, the condition is that a and B are coprime, otherwise they can be reduced to the simplest fraction

A divided by B is a part of B

Not necessarily
From a divided by B, we can know that B is not equal to 0, so when a = 0, a △ B = 0
When a is equal to 0, a △ B = A / b

If a △ B = 35, then a is 35 of B______ (judge right or wrong)

The analysis shows that if a △ B = 35, then a is 35 of B

A × (7 + b), when a = 5, B=______ So that a × (7 + b) = 52.5

Substituting a = 5 into: a × (7 + b) = 52.5, we can get: 5 × (7 + b) = 52.5, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 7 + B = 10.5, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; b = 3.5; so the answer is: 3.5
