Question

-1/15×-10/13=2/39 is this correct?

Answer 1

Yes you are correct! :)

Step 1. Simplify
`(1)/(15) * (-10)/(13)` to
`- (1)/(15)* (10)/(13)`


`(1)/(15) * (10)/(13)`


Step 2. Apply this rule
`(a)/(b) * (c)/(d) = (ac)/(db)`


`(1*10)/(15*13)`

Step 3. Simplify
`1*10` to
`10`


`(10)/(15*13)`

Step 4. Simplify
`15*13` to
`195`


`(10)/(195)`

Step 5. Simplify


`(2)/(39)`

Done! :) Your answer is
`(2)/(39)`
