What is 9/24 plus 2/4? (Answer: 7/8)

Exact Answer

==================================================
Problem: What is 9/24 plus 2/4?
Formula / Expression: 9/24 + 2/4
Final Answer: 7/8
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
Notice that 24 is an exact multiple of 4 (4 × 6 = 24). The Least Common Denominator (LCD) is simply 24, meaning we only need to scale one fraction.
Working: LCD(24, 4) = 24

Step 2: Convert to Equivalent Fractions with Common Denominator 24
Multiply the numerator and denominator of 9/24 by 1, and multiply the numerator and denominator of 2/4 by 6 so both fractions share the common base 24.
Working: 9 × 1/24 × 1 = 9/24 and 2 × 6/4 × 6 = 12/24

Step 3: Add the Numerators
Now add the numerators (9 + 12 = 21) and keep the common denominator 24 unchanged.
Working: 9 + 12/24 = 21/24

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 21 and 24, which is 3. Divide both the numerator and denominator by 3.
Working: 21 ÷ 3/24 ÷ 3 = 7/8

Step 5: Decimal & Percentage Representation
Dividing the numerator 7 by denominator 8 yields an exact terminating decimal of 0.875 (or 87.5%).
Working: 7 ÷ 8 = 0.875 (87.5%)

Key Values:
- Simplified Fraction: 7/8
- Mixed Number Form: 7/8
- Decimal Value: 0.875
- Percentage: 87.5%

Step-by-Step Solution: 9/24 + 2/4

Step 1

Find the Least Common Denominator (LCD)

Notice that 24 is an exact multiple of 4 (4 × 6 = 24). The Least Common Denominator (LCD) is simply 24, meaning we only need to scale one fraction.

LCD(24, 4) = 24

Step 2

Convert to Equivalent Fractions with Common Denominator 24

Multiply the numerator and denominator of 9/24 by 1, and multiply the numerator and denominator of 2/4 by 6 so both fractions share the common base 24.

9 × 1/24 × 1 = 9/24 and 2 × 6/4 × 6 = 12/24

Step 3

Add the Numerators

Now add the numerators (9 + 12 = 21) and keep the common denominator 24 unchanged.

9 + 12/24 = 21/24

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 21 and 24, which is 3. Divide both the numerator and denominator by 3.

21 ÷ 3/24 ÷ 3 = 7/8

Step 5

Decimal & Percentage Representation

Dividing the numerator 7 by denominator 8 yields an exact terminating decimal of 0.875 (or 87.5%).

7 ÷ 8 = 0.875 (87.5%)
