2.145 is divisible by which numbers<br> 2<br> 6<br> 5<br> 3​
mariarad [96]

Answer:

  • 3 and 5 if "." marks thousands
  • 2, 3, 5, 6 if "." is a decimal point

Step-by-step explanation:

The number 2145 is not even, so will not be divisible by 2 or 6. It ends in 5 so is divisible by 5. Its sum of digits is 12, which is divisible by 3, so the number is divisible by 3.

2145 is divisible by 3 and 5.

2.145 is divisible by all of these numbers:

  2.145/2 = 1.0725

  2.145/6 = 0.3575

  2.145/5 = 0.429

  2.145/3 = 0.715

_____

Here, we take the mixed number to be divisible if the decimal representation of the quotient is a terminating decimal fraction.

3(300) = 900x

900=900x

x=1
