To find \( 720 \div 8 \) using mental math, you can think of it as follows:
First, break down the numbers:
1. \( 720 \) can be thought of as \( 720 = 70 \times 10 + 2 \times 10 \), or simply just recognize it's 72 tenths.
2. Then, divide \( 72 \) by \( 8 \).
Calculating \( 72 \div 8 = 9 \).
Now, since we are dividing \( 720 \) by \( 8 \):
1. The operation becomes \( 720 \div 8 = 90 \).
Thus, the answer is:
**90**.
