Exact Answer

==================================================
Problem: What is 5/48 plus 10/21?
Formula / Expression: 5/48 + 10/21
Final Answer: 65/112
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 48 and 21 share a common factor (GCD = 3). Finding their Least Common Multiple gives an LCD of 336 (which is smaller than their product 48 × 21 = 1008, keeping the calculation simpler).
Working: LCD(48, 21) = 336

Step 2: Convert to Equivalent Fractions with Common Denominator 336
Multiply the numerator and denominator of 5/48 by 7, and multiply the numerator and denominator of 10/21 by 16 so both fractions share the common base 336.
Working: 5 × 7/48 × 7 = 35/336 and 10 × 16/21 × 16 = 160/336

Step 3: Add the Numerators
Now add the numerators (35 + 160 = 195) and keep the common denominator 336 unchanged.
Working: 35 + 160/336 = 195/336

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 195 and 336, which is 3. Divide both the numerator and denominator by 3.
Working: 195 ÷ 3/336 ÷ 3 = 65/112

Step 5: Decimal & Percentage Representation
Dividing the numerator 65 by denominator 112 produces a repeating decimal (approximately 0.580357, or 58.0357%).
Working: 65 ÷ 112 = 0.580357 (58.0357%)

Key Values:
- Simplified Fraction: 65/112
- Mixed Number Form: 65/112
- Decimal Value: 0.580357
- Percentage: 58.0357%

Step-by-Step Solution: 5/48 + 10/21

Step 1

Find the Least Common Denominator (LCD)

The denominators 48 and 21 share a common factor (GCD = 3). Finding their Least Common Multiple gives an LCD of 336 (which is smaller than their product 48 × 21 = 1008, keeping the calculation simpler).

LCD(48, 21) = 336

Step 2

Convert to Equivalent Fractions with Common Denominator 336

Multiply the numerator and denominator of 5/48 by 7, and multiply the numerator and denominator of 10/21 by 16 so both fractions share the common base 336.

5 × 7/48 × 7 = 35/336 and 10 × 16/21 × 16 = 160/336

Step 3

Add the Numerators

Now add the numerators (35 + 160 = 195) and keep the common denominator 336 unchanged.

35 + 160/336 = 195/336

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 195 and 336, which is 3. Divide both the numerator and denominator by 3.

195 ÷ 3/336 ÷ 3 = 65/112

Step 5

Decimal & Percentage Representation

Dividing the numerator 65 by denominator 112 produces a repeating decimal (approximately 0.580357, or 58.0357%).

65 ÷ 112 = 0.580357 (58.0357%)
