plz help me!!​

Answer 1

Step-by-step explanation:

lets consider the number be x

(i) 5.233333

x = 5.2333

we have to try to put the reoccurring number before decimal once so we will multiply it by 10

10x = 52.3333

still the reoccurring number is not before decimal so we will multiply it with 10 again

100x = 523.3333

now subtract the old number with new one

100x - 10x = 523.3333 - 52.3333

90x = 471

x = 471/90

solve another one as same
