Step-by-Step Solution: 16/34 + 7/13

Step 1

Find the Least Common Denominator (LCD)

The denominators 34 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 34 ร— 13 = 442.
LCD(34, 13) = 442
Step 2

Convert to Equivalent Fractions with Common Denominator 442

Multiply the numerator and denominator of 16/34 by 13, and multiply the numerator and denominator of 7/13 by 34 so both fractions share the common base 442.
16 ร— 13/34 ร— 13 = 208/442   and   7 ร— 34/13 ร— 34 = 238/442
Step 3

Add the Numerators

Now add the numerators (208 + 238 = 446) and keep the common denominator 442 unchanged.
208 + 238/442 = 446/442
Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 446 and 442, which is 2. Divide both the numerator and denominator by 2.
446 รท 2/442 รท 2 = 223/221
Step 5

Since the numerator (223) is greater than the denominator (221), divide 223 by 221: it goes in 1 whole time(s) with a remainder of 2, giving the mixed number 1 2/221.
223/221 = 12/221
Step 6

Decimal & Percentage Representation

Dividing the numerator 223 by denominator 221 produces a repeating decimal (approximately 1.00905, or 100.905%).
223 รท 221 = 1.00905 (100.905%)
