85 -21 = 3x
60=3x
20 = x

3 3/4 pounds so 3×3/4 = 2 1/4(mixed fraction)
2 1/4÷ 1/8= 2 1/4 × 8/1
for fraction division, yo
u keep the first fraction and flip the second fraction around. than you change the divide sign to multiply sign to find the answer
In the first 10 -> 10 - 9 = 1 (contain a 3).
In the first 100 -> 100 - 9 * 9 = 19 (contain a 3).
In the first 10^n ->
10^n - 9^n (contain a 3).
<u>The answer is 3.439 numbers contain a 3 in the first 10.000</u>
