Key Insights
First, compute the denominator:
0,42 + 0,12 = 0,54
Now substitute back:
0,42 / 0,54
This fraction can be simplified — both numerator and denominator share common factors when expressed as integers. Converting 0.42 and 0.54 to whole numbers removes decimal places:
0.42 = 42 / 100,
0.54 = 54 / 100.
So,
(42 / 100) ÷ (54 / 100) = (42 / 100) × (100 / 54) = 42 / 54

Now simplify 42 / 54 by dividing numerator and denominator by their greatest common divisor (GCD), which is 6:
42 ÷ 6 = 7,
54 ÷ 6 = 9 → simplifies to 7/9
Why 7/9 ≈ 0,7778
Now convert 7/9 to decimal:
7 ÷ 9 ≈ 0.777777...
This repeating decimal rounds naturally to 0.7778, matching the approximate value mentioned. This shows how exact fractions can be expressed as recurring decimals — a key concept in mathematical reasoning.
