Multiply 2.5 by 3.4.

• 8.5

• 7.5

• 8.0

• 6.5

Answer explanation

To multiply 2.5 by 3.4, multiply the two numbers together, ignoring the decimal points: 25 * 34 = 850. Looking at the original numbers with the decimal points, you should see a total of two decimal place values between both numbers. Add in two decimal place values into 850 starting from the right to get 8.5 (8.50 with the zero, but the zero is not needed.)
