Alright, let's begin! We start with 37.8 and then divide it with..7.6! Now, we try to get the answer of that.

37.8 ÷ 7.6 = 4.973.

However, we need to bring it down to an estimate. It would then be 4.97. Although, we need to also see if our answer is correct.

4.97 × 7.6 = 37.7

There is more answers closer to the number but this should be the correct answer due to it being the answer of all the steps I used.

But wait! We need the round the answer to the nearest whole number. So, it would be 38.

So, overall, it will be 38 cotton swabs tall.

Hope this helps!
