First estimate using front-end rounding and then multiply. (See Example.)
First estimate using front-end rounding and then multiply. (See Example.)      Multiplying Decimals  Multiply each of the following. (a) 8.34 × 4.2 (b).032 ×.07 SOLUTION  (a) First multiply the given numbers as if they were whole numbers.     There are two decimal places in 8.34 and one in 4.2. This means that there are 2 + 1=3 decimal places in the final answer. Find the final answer by starting at the right and counting three places to the left: 35.028 3 places to the left (b) Here, it is necessary to attach zeros at the left in the answer:
