Solve the following decimal operations: a) 23.4 + 17.56, b) 45.7 - 18.92, c) 6.25 x 4. Then solve: a) 12.6 / 3, b) 45.5 / 5. Finally, convert decimals to fractions: a) 0.25, b) 0.6, c) 1.75.

Here are the solutions to the questions: Question 3 a) Step 1: Add the decimals. 23.4 + 17.56 = 40.96 The sum is 40.96. b) Step 1: Subtract the decimals. 45.7 - 18.92 = 26.78 The difference is 26.78. c) Step 1: Multiply the numbers. 6.25 × 4 = 25.00 The product is 25. Question 4 a) Step 1: Divide the decimal by 3. 12.6 ÷ 3 = 4.2 The quotient is 4.2. b) Step 1: Divide the decimal by 5. 45.5 ÷ 5 = 9.1 The quotient is 9.1. Question 5 a) Step 1: Write the decimal as a fraction. 0.25 = (25)/(100) Step 2: Simplify the fraction by dividing the numerator and denominator by their greatest common divisor, which is 25. (25)/(100) = (25 ÷ 25)/(100 ÷ 25) = (1)/(4) The fraction is (1)/(4). b) Step 1: Write the decimal as a fraction. 0.6 = (6)/(10) Step 2: Simplify the fraction by dividing the numerator and denominator by their greatest common divisor, which is 2. (6)/(10) = (6 ÷ 2)/(10 ÷ 2) = (3)/(5) The fraction is (3)/(5). c) Step 1: Write the decimal as a mixed number or improper fraction. 1.75 = 1(75)/(100) Step 2: Simplify the fractional part (75)/(100) by dividing the numerator and denominator by their greatest common divisor, which is 25. (75)/(100) = (75 ÷ 25)/(100 ÷ 25) = (3)/(4) Step 3: Combine the whole number and the simplified fraction. 1(3)/(4) = (1 × 4 + 3)/(4) = (7)/(4) The fraction is (7)/(4). Question 6 a) Step 1: Multiply the cost of one packet by the number of packets. Cost of 4 packets = R12.50 × 4 = R50.00 The cost of 4 packets is R50.00. b) Step 1: Subtract the total cost from the amount paid. Change received = R100.00 - R50.00 = R50.00 The change received will be R50.00. Send me the next one 📸
