Question

Suppose a-b=0a−b=0a, minus, b, equals, 0 and a,b\ne0a,b≠0a, comma, b, does not equal, 0. which one of these expressions equals \dfrac{b}{a} a b ​ start fraction, b, divided by, a, end fraction ?

Answer 1

Answer:

it is given that

a-b=0

Adding , b to both sides

→a-b+b=0+b

→a=b

Dividing both sides by , b we get

$\frac{b}{a}=\frac{b}{b}\\\\ \frac{b}{a}=1$

So,Among the expression given above, which is equivalent to $\frac{b}{a}$

Option 1: a-b=0

Answer 2

the answer is $\frac{a}{b}$
