$\huge\boxed{\mathbb{\fcolorbox{red}{yellow}{HEY MATE}}}$

$<i><font face=Times New Roman size=4>$
1) 36/81 = x/63

=> 81 × x = 36 × 63

=> 81x = 36 × 63

=> x = (36 × 63)/81

=> x = 28

...........................................

2) 27/x = 63/84

=> 63 × x = 27 × 84

=> 63x = 27 × 84

=> x = (27 × 84)/63

=> x = 36

...........................................

3) 25/35 = 35/x

=> 25 × x = 35 × 35

=> 25x = 35 × 35

=> x = (35 × 35)/25

=> x = 49

Answer 2

a) 36*63 = 81*x
2268 = 81x
2268/81 = x
28 = x
b) 27*84 = x*63
2268 = 63x
2268/63 = x
36 = x
c) 25*x = 35*35
25x = 1225
x = 49
