What is 3/8 divided by 1/3? (Answer: 9/8)

Exact Answer

==================================================
Problem: What is 3/8 divided by 1/3?
Formula / Expression: 3/8 ÷ 1/3
Final Answer: 1 1/8 (9/8)
==================================================

Step-by-Step Solution:

Step 1: Find the Reciprocal of the Second Fraction
Dividing by a fraction is equivalent to multiplying by its reciprocal ("Keep, Change, Flip"). Invert the second fraction 1/3 to get 3/1.
Working: 3/8 ÷ 1/3 = 3/8 × 3

Step 2: Multiply the Numerators and Denominators
Multiply the new numerators (3 × 3 = 9) and denominators (8 × 1 = 8).
Working: 3 × 3/8 × 1 = 9/8

Step 3: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 9 and 8 is 1, confirming that 9/8 cannot be reduced further—it is already in its simplest irreducible form.
Working: 9/8

Step 4: Convert Improper Fraction to a Mixed Number
Since the numerator (9) is greater than the denominator (8), divide 9 by 8: it goes in 1 whole time(s) with a remainder of 1, giving the mixed number 1 1/8.
Working: 9/8 = 1 1/8

Step 5: Decimal & Percentage Representation
Dividing the numerator 9 by denominator 8 yields an exact terminating decimal of 1.125 (or 112.5%).
Working: 9 ÷ 8 = 1.125 (112.5%)

Key Values:
- Simplified Fraction: 9/8
- Mixed Number Form: 1 1/8
- Decimal Value: 1.125
- Percentage: 112.5%

9/8

Step 4

Convert Improper Fraction to a Mixed Number

Since the numerator (9) is greater than the denominator (8), divide 9 by 8: it goes in 1 whole time(s) with a remainder of 1, giving the mixed number 1 1/8.

9/8 = 11/8

Step 5

Decimal & Percentage Representation

Dividing the numerator 9 by denominator 8 yields an exact terminating decimal of 1.125 (or 112.5%).

9 ÷ 8 = 1.125 (112.5%)
