What is 2/4 plus 11/16? (Answer: 19/16)

Exact Answer

==================================================
Problem: What is 2/4 plus 11/16?
Formula / Expression: 2/4 + 11/16
Final Answer: 1 3/16 (19/16)
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
Notice that 16 is an exact multiple of 4 (4 × 4 = 16). The Least Common Denominator (LCD) is simply 16, meaning we only need to scale one fraction.
Working: LCD(4, 16) = 16

Step 2: Convert to Equivalent Fractions with Common Denominator 16
Multiply the numerator and denominator of 2/4 by 4, and multiply the numerator and denominator of 11/16 by 1 so both fractions share the common base 16.
Working: 2 × 4/4 × 4 = 8/16 and 11 × 1/16 × 1 = 11/16

Step 3: Add the Numerators
Now add the numerators (8 + 11 = 19) and keep the common denominator 16 unchanged.
Working: 8 + 11/16 = 19/16

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 19 and 16 is 1, confirming that 19/16 cannot be reduced further—it is already in its simplest irreducible form.
Working: 19/16

Step 5: Convert Improper Fraction to a Mixed Number
Since the numerator (19) is greater than the denominator (16), divide 19 by 16: it goes in 1 whole time(s) with a remainder of 3, giving the mixed number 1 3/16.
Working: 19/16 = 1 3/16

Step 6: Decimal & Percentage Representation
Dividing the numerator 19 by denominator 16 yields an exact terminating decimal of 1.1875 (or 118.75%).
Working: 19 ÷ 16 = 1.1875 (118.75%)

Key Values:
- Simplified Fraction: 19/16
- Mixed Number Form: 1 3/16
- Decimal Value: 1.1875
- Percentage: 118.75%

Step-by-Step Solution: 2/4 + 11/16

Step 1

Find the Least Common Denominator (LCD)

Notice that 16 is an exact multiple of 4 (4 × 4 = 16). The Least Common Denominator (LCD) is simply 16, meaning we only need to scale one fraction.

LCD(4, 16) = 16

Step 2

Convert to Equivalent Fractions with Common Denominator 16

Multiply the numerator and denominator of 2/4 by 4, and multiply the numerator and denominator of 11/16 by 1 so both fractions share the common base 16.

2 × 4/4 × 4 = 8/16 and 11 × 1/16 × 1 = 11/16

Step 3

Add the Numerators

Now add the numerators (8 + 11 = 19) and keep the common denominator 16 unchanged.

8 + 11/16 = 19/16

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 19 and 16 is 1, confirming that 19/16 cannot be reduced further—it is already in its simplest irreducible form.

19/16

Step 5

Convert Improper Fraction to a Mixed Number

Since the numerator (19) is greater than the denominator (16), divide 19 by 16: it goes in 1 whole time(s) with a remainder of 3, giving the mixed number 1 3/16.

19/16 = 13/16

Step 6

Decimal & Percentage Representation

Dividing the numerator 19 by denominator 16 yields an exact terminating decimal of 1.1875 (or 118.75%).

19 ÷ 16 = 1.1875 (118.75%)
