Selepe, let's continue with these Grade 7 Mathematics problems. Section A 1.6 Given: 32,27539. Round off to 2 decimal places. Step 1: Identify the digit in the second decimal place, which is 7. Step 2: Look at the digit immediately to its right, which is 5. Step 3: Since this digit (5) is 5 or greater, we round up the digit in the second decimal place. Step 4: The 7 becomes an 8. The number rounded to 2 decimal places is 32,28. Comparing this with the given options, the correct option is C. C 1.7 √(5² + 12²) = Step 1: Calculate the squares of the numbers inside the square root. 5² = 5 × 5 = 25; 12² = 12 × 12 = 144 Step 2: Add the squared values. 25 + 144 = 169 Step 3: Find the square root of the sum. √(169) = 13 Comparing this with the given options, the correct option is A. A 1.8 Given integers: −110; 100; −120; 80. Which one of the above integers is the smallest? Step 1: Identify the positive and negative integers. Positive integers: 100, 80. Negative integers: −110, −120. Step 2: Remember that negative numbers are always smaller than positive numbers. Step 3: Compare the negative integers. The further a negative number is from zero (i.e., the larger its absolute value), the smaller it is. |−110| = 110; |−120| = 120 Since 120 > 110, −120 is smaller than −110. Therefore, −120 is the smallest integer. Comparing this with the given options, the correct option is C. C
