- 100000 ÷ 3125 = 32
✅ Final Simplified Fraction
0.71875 as a fraction (simplest form):
23/32
Step 3: Verify the Result
Decimal Verification
Divide the numerator by the denominator:
23 ÷ 32 = 0.71875
✔ Verified
Cross-Multiplication Check
- 23 × 100000 = 2,300,000
- 71875 × 32 = 2,300,000
✔ Both results match, confirming accuracy.
Is 23/32 the Simplest Form?
Yes.
The numbers 23 and 32 have no common factors other than 1, so the fraction is already fully simplified.
