Question

Can someone help me with these. it’ll be better if u edit on it but it optional!

Answer 1

Hey there mate :)

When a number is multiplied by a fraction equal to 1, the value of the number remains the same.

Using this, we can find the values:-

Image 2 answers :

`(4)/(5) * (4)/(4) = (4)/(5)`

When we cancel the same 4 of LHS remaining we get as 4/5. By doing the same method, we can find the remaining answers.

`(2)/(3) * (7)/(7) = (2)/(3) \\ \\ (5)/(6) * (8)/(8) = (5)/(6) \\ \\ (3)/(4) * (5)/(5)`

Image 1 answers :

`(2)/(3) * (4)/(2) = (4)/(3)`

Here, cancel the common numbers in LHS and write back the remaining uncancelled numbers to get 4/3 in RHS.

Using same method,

`(3)/(4) * (5)/(3) = (5)/(4)`

Next, Now in last two questions, we have to do a little differently. Till this much time we did by cancelling the common numbers. So, multiply the numerator and denominator.

`(1)/(4) * (3)/(2) \\ = > (1 * 3)/(4 * 2) \\ = > (3)/(8)`

So, above question's answer is 3/8.

Likewise, using the same method, find the next question :-

`(2)/(5) * (4)/(3) \\ = > (2 * 4)/(5 * 3) \\ = > (8)/(15)`

So, next answer is 8/15.

Hope this Helps...
