When we need to find 10% of any number we simply move our decimal point one place values to the left.Original: 2,300,0001st Place: 230,000.0So 10% of 2,300,000 is 230,000. Now 5% is exactly half of our 10%.230,000 ÷ 2 = 115,000Lastly, add together our 5% and 10%.230,000 + 115,000 = 345,000Therefore 15% of 2.3 million dollars is $345,000.
