Download Solution PDFGiven:
0.527 - 0.325 + 0.224 = ?
Formula used:
A repeating decimal 0.abc can be written as (abc - a) / 990
A repeating decimal 0.ab can be written as ab / 99
Calculation:
0.527 = (527 - 5) / 990 = 522 / 990
0.325 = (325 - 3) / 990 = 322 / 990
0.224 = (224 - 2) / 990 = 222 / 990
⇒ ? = 522 / 990 - 322 / 990 + 222 / 990
⇒ ? = (522 - 322 + 222) / 990
⇒ ? = (200 + 222) / 990
⇒ ? = 422 / 990
The correct answer is Option (1).
