Step 1: Set up long multiplication. Ignore the decimals for now (we deal with those later when we multiply).
 11ec0fda_98e3_67f5_a67f_fd169ed80650_NR0004_00 Step 2: Multiply from right to left. 5 x 4 = 20. Since 20 is two digits, we carry the first digit (2) to the next column.
 11ec0fda_98e3_67f6_a67f_e5ff39efd082_NR0004_00 Step 3: Calculate 5 x 5 = 25. Now add the carry digit 25 + 2 = 27. Since 27 is two digits, we carry the first digit (2) to the next column.
 11ec0fda_98e3_67f7_a67f_897161d7a4b6_NR0004_00 Step 4: Since we are done multiplying the top number by 5, we can bring down our carry digit of 2.
 11ec0fda_98e3_67f8_a67f_c9142c8cd595_NR0004_00 Step 5: Begin multiplying the top number by the next digit in the bottom number (6). 6 x 4 = 24. Since 24 is two digits, we carry the first digit (2) to the next column. Remember to enter a 0 as a placeholder in the last digit.
 11ec0fda_98e3_67f9_a67f_a9954de15b61_NR0004_00 Step 6: Calculate 6 x 5 = 30. Now we add the carry digit 30 + 2 = 32. Since 32 is two digits, we carry the first digit (3) to the next column.
 11ec0fda_98e3_67fa_a67f_cdbdbfc1ec35_NR0004_00 Step 7: Since we are done multiplying the top number by 5, we can bring down our carry digit of 3.
 11ec0fda_98e3_67fb_a67f_6f7a1407e333_NR0004_00 Step 8: We now add the products (270 + 3240) to get the final answer.
 11ec0fda_98e3_67fc_a67f_f97af013d2e8_NR0004_00 Step 9: To place the decimal, count the number of digits to the right of the decimal in the problem. The total of those digits is how many spaces should come after the decimal in your answer.
 11ec0fda_98e3_67fd_a67f_7b007fac9f79_NR0004_00 Since trailing zeroes after the decimal can be dropped, our answer of 3.510 can be written simply as 3.51.
