Answer: 1.5625 = 1 9/16
Step-by-step explanation:
1.) 1.5625 = 1.5625/1
2.) 1.5625/1 × 1.5625/10000 = 15625/10000 (multiplied 10^4 to remove the four decimal places)
3.) 15625/10000 ÷ 625/625 = 25/16 (find the greatest common factor of 15,625 and 10,000, then divide it)
4.) 25/16 = 1 9/16 (simplify the improper fraction)
