Answer 1

There will be different approaches. All as effective as each other. Here is another one

21.39

#0.31" is "31/(color(magenta)(100)#
Consider #x xx31 =( x xx3xx10) +x#
So #[color(white)(.)(69xx3xx10) +69color(white)(.)]color(magenta)(-:100) =2139/100 = 21.39#

#0.31 * 69 = 21.39#

If you are calculating it in your head, you might be best off doubling #69# five times, subtracting #69#, then dividing by #100#, since #2^5=32#
#69 -> 138 -> 276 -> 552 -> 1104 -> 2208 -> 2139 -> 21.39#

Answer 4

To multiply 0.31 by 69, you can follow these steps:

  1. Ignore the decimal points for now and multiply 31 by 69.
  2. 31 multiplied by 69 equals 2139.
  3. Now, count the total number of decimal places in the numbers being multiplied. In this case, there are 2 decimal places (1 in 0.31 and none in 69).
  4. Add the total number of decimal places, which is 2, to the result obtained in step 2. This gives us 2139.00.
  5. Finally, place the decimal point in the answer according to the total number of decimal places. So, 0.31 multiplied by 69 equals 21.39.
