Q
Q: In a recent climate change agreement, 12 countries committed to reducing emissions by 20%. If the total emissions are 1 billion tons, how much will be reduced?
Solution: Reduction in emissions = 20% of 1 billion tons = 0.2 * 1 billion = 200 million tons.
Steps: 6
Step 1: Understand that 20% means 20 out of every 100 parts.
Step 2: Convert 20% into a decimal. 20% as a decimal is 0.2.
Step 3: Know that the total emissions are 1 billion tons.
Step 4: To find the reduction, multiply the total emissions by the decimal: 0.2 * 1 billion tons.
Step 5: Calculate the multiplication: 0.2 * 1 billion = 200 million tons.
Step 6: Conclude that the emissions will be reduced by 200 million tons.
