Answer 2

x = 0.4233333.....••••eq1

multiply by 100 on both sides

100x = 42.3333...••••••eq2

multiply by 1000 in eq1 on both sides

1000x = 423.33333.....•••••••eq3

eq3 – eq2

1000x – 100x = 423.33333 – 42.33333

900x = 381

x = 381/900 = 127/300

x = 127/300

0.4233333... in p/q = 127/300

hope it helps you....
