For The first question, The answer is :
![45.](https://img.qammunity.org/2020/formulas/mathematics/middle-school/swctmtrewzf30kr1x59geh3wkxfstnmpxz.png)
You have to factor the numerator and the denominator and cancel the common factors.
For the second question, The answer is :
![(1)/(2).](https://img.qammunity.org/2020/formulas/mathematics/middle-school/6dlonyhq7p0lc63s1q9gy7a1snm5wna23b.png)
You have to Reduce the expression, If possible, By cancelling the common factors.
For the Third question, The answer is :
![144.](https://img.qammunity.org/2020/formulas/mathematics/middle-school/g1o9mcd5z7h5t1gigztnsuh36grtz948tx.png)
Just like the first one, You have to factor the numerator and the denominator and cancel the common factors.
And For the fourth question, The answer is :
![(7)/(4).](https://img.qammunity.org/2020/formulas/mathematics/middle-school/2wjh33ap5bur3pirr0mjuzsdrkuqprh60p.png)
and again, just like the second one, You have to Reduce the expression, If possible, By cancelling the common factors.
