Another one Connizer — let's solve it. 1.1.1 Step 1: Perform the operation inside the parentheses. (8+19) - 54 ÷ 2 = 27 - 54 ÷ 2 Step 2: Perform the division. 27 - 27 Step 3: Perform the subtraction. 0 The answer is 0. 1.1.2 Step 1: Perform the multiplication. (1)/(2) × 500 - (-250) = 250 - (-250) Step 2: Subtracting a negative number is equivalent to adding the positive number. 250 + 250 Step 3: Perform the addition. 500 The answer is 500. 1.1.3 Step 1: Calculate the division to get the decimal. 150 ÷ 450 = (150)/(450) = (1)/(3) ≈ 0.3333... Step 2: Convert the decimal to a percentage by multiplying by 100. 0.3333... × 100\% ≈ 33.33\% The answer is approximately 0.33 and 33.33\%. 1.2 To arrange the numbers 0; -32; 6; 20 in descending order, we list them from largest to smallest. The order is 20; 6; 0; -32. 1.3.1 Step 1: Identify the pattern. The sequence is 9; 18; 36; .... Each term is multiplied by 2 to get the next term (9 × 2 = 18, 18 × 2 = 36). Step 2: Apply the pattern to find the next two numbers. The next number is 36 × 2 = 72. The number after that is 72 × 2 = 144. The missing numbers are 72; 144. 1.3.2 Step 1: Identify the pattern. The sequence is 27; 9; 3; .... Each term is divided by 3 to get the next term (27 ÷ 3 = 9, 9 ÷ 3 = 3). Step 2: Apply the pattern to find the next two numbers. The next number is 3 ÷ 3 = 1. The number after that is 1 ÷ 3 = (1)/(3). The missing numbers are 1; (1)/(3). 1.3.3 Step 1: Check for constant difference. 9 - 27 = -18 3 - 9 = -6 The difference is not constant. Step 2: Check for constant ratio. (9)/(27) = (1)/(3) (3)/(9) = (1)/(3) The ratio is constant. The pattern in 1.3.2 is an example of a constant ratio. This is because each term is obtained by multiplying the previous term by a constant factor of (1)/(3) (or dividing by 3). 1.4 Step 1: Recall the conversion factor between kilometers and meters. 1 km = 1000 m Step 2: Multiply the given value in kilometers by the conversion factor. 3.86 km × 1000 mkm = 3860 m The answer is 3860 m.
