Step-by-step explanation:

Answer 2

Here we go!

Starting at 501, we have 20 sixes to get to 600. There is one six for every ten, and an extra for all of the numbers that start with 60. (506, 516, 526, 536, 546, 556, 560, 561, 562, 563, 564, 565, 566, 567, 568, 569, 576, 586, 596)

At 600, every number has at least one six except 700. That makes for 99 sixes.

After that, we know we have 20 extra sixes from the ones place and tens place. 99 + 20 = 119.

Total = 119 + 20  = 139 sixes

Hope it helps...
