Step by step solution
1. Round each number to 1 significant figure:
- \(6.8\) rounded to 1 significant figure is \(7\) because the first non-zero digit is 6 and the next digit (8) rounds up.
- \(10.6\) rounded to 1 significant figure is \(10\) because \(10.6 = 1.06 \times 10^1\) and rounding to 1 significant figure gives \(1 \times 10^1 = 10\).
- \(3.2\) rounded to 1 significant figure is \(3\) because the first digit is 3 and the next digit (2) rounds down.
- \(0.98\) rounded to 1 significant figure is \(1\) because \(0.98\) is closer to 1 than 0.9 when rounded to 1 significant figure.
2. Substitute rounded values into the calculation:
Numerator: \(7 \times 10 = 70\)
Denominator: \(3 - 1 = 2\)
3. Divide the rounded numerator by the rounded denominator:
\(\frac{70}{2} = 35\)
Final answer \(35\)
