What is 10/16 plus 2/3? (Answer: 31/24)

Exact Answer

==================================================
Problem: What is 10/16 plus 2/3?
Formula / Expression: 10/16 + 2/3
Final Answer: 1 7/24 (31/24)
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 16 and 3 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 16 × 3 = 48.
Working: LCD(16, 3) = 48

Step 2: Convert to Equivalent Fractions with Common Denominator 48
Multiply the numerator and denominator of 10/16 by 3, and multiply the numerator and denominator of 2/3 by 16 so both fractions share the common base 48.
Working: 10 × 3/16 × 3 = 30/48 and 2 × 16/3 × 16 = 32/48

Step 3: Add the Numerators
Now add the numerators (30 + 32 = 62) and keep the common denominator 48 unchanged.
Working: 30 + 32/48 = 62/48

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 62 and 48, which is 2. Divide both the numerator and denominator by 2.
Working: 62 ÷ 2/48 ÷ 2 = 31/24

Step 5: Convert Improper Fraction to a Mixed Number
Since the numerator (31) is greater than the denominator (24), divide 31 by 24: it goes in 1 whole time(s) with a remainder of 7, giving the mixed number 1 7/24.
Working: 31/24 = 1 7/24

Step 6: Decimal & Percentage Representation
Dividing the numerator 31 by denominator 24 produces a repeating decimal (approximately 1.291667, or 129.1667%).
Working: 31 ÷ 24 = 1.291667 (129.1667%)

Key Values:
- Simplified Fraction: 31/24
- Mixed Number Form: 1 7/24
- Decimal Value: 1.291667
- Percentage: 129.1667%

Step-by-Step Solution: 10/16 + 2/3

Step 1

Find the Least Common Denominator (LCD)

The denominators 16 and 3 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 16 × 3 = 48.

LCD(16, 3) = 48

Step 2

Convert to Equivalent Fractions with Common Denominator 48

Multiply the numerator and denominator of 10/16 by 3, and multiply the numerator and denominator of 2/3 by 16 so both fractions share the common base 48.

10 × 3/16 × 3 = 30/48 and 2 × 16/3 × 16 = 32/48

Step 3

Add the Numerators

Now add the numerators (30 + 32 = 62) and keep the common denominator 48 unchanged.

30 + 32/48 = 62/48

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 62 and 48, which is 2. Divide both the numerator and denominator by 2.

62 ÷ 2/48 ÷ 2 = 31/24

Step 5

Convert Improper Fraction to a Mixed Number

Since the numerator (31) is greater than the denominator (24), divide 31 by 24: it goes in 1 whole time(s) with a remainder of 7, giving the mixed number 1 7/24.

31/24 = 17/24

Step 6

Decimal & Percentage Representation

Dividing the numerator 31 by denominator 24 produces a repeating decimal (approximately 1.291667, or 129.1667%).

31 ÷ 24 = 1.291667 (129.1667%)
