Question

What is the product a-3/15a times 5/a-3

Answer 1

Answer:-1/(a^2 -3a)
Solution :

-3/15a × 5/a-3
= -3/3a × 1/a-3
=-1/a × 1/a-3
=-1/a(a-3)
=-1/(a^2 -3a)

Answer 2

For this case we must find the following product:

`\frac {a-3} {15a} * \frac {5} {a-3} = \frac {5 (a-3)} {15a (a-3)}`

We know that
`\frac {(a-3)} {(a-3)} = 1`

So:

`\frac {5 (a-3)} {15a (a-3)} = \frac {5} {15a}`

Dividing the numerator and denominator by "5":

`\frac {5} {15a} = \frac {1} {3a}`

Thus, the product is
`\frac {1} {3a}`

Answer:

`\frac {1} {3a}`
