Questions & Step-by-Step Solutions

A country aims to reduce its greenhouse gas emissions by 30% over the next 5 years. If the current emissions are 1,200 million tons, what will be the target emissions?
  • Step 1: Identify the current emissions, which are 1,200 million tons.
  • Step 2: Calculate 30% of the current emissions. This is done by multiplying 1,200 million tons by 30/100.
  • Step 3: Perform the multiplication: 1,200 * 30/100 = 360 million tons.
  • Step 4: Subtract the 30% reduction (360 million tons) from the current emissions (1,200 million tons).
  • Step 5: Perform the subtraction: 1,200 - 360 = 840 million tons.
  • Step 6: The target emissions after the reduction will be 840 million tons.
  • Percentage Reduction – Understanding how to calculate a percentage of a total and apply it to find a new value.
  • Basic Arithmetic – Performing subtraction and multiplication to arrive at the final answer.
