Answer:

69

Step-by-step explanation:

  • Let x is the ones digit
  • Let y is the tens digit

Given that:

  • You use a total of 15 base ten blocks to show this number:

<=> x + y = 15 (1)

  • One of the digits is 6, so substitute into (1) we have another digit equals to: 9
  • Because the number of ones block is greater than the number of ten blocks

<=> y > x

<=> y = 9 and x= 6

So that number is: 69.
