1. The problem asks to write 64 thousandths in decimal form. 2. "Thousandths" means parts out of 1000, so 64 thousandths is \( \frac{64}{1000} \). 3. To convert \( \frac{64}{1000} \) to decimal, divide 64 by 1000. 4. Dividing 64 by 1000 moves the decimal point three places to the left: \(64 = 64.0\) becomes \(0.064\). 5. Therefore, 64 thousandths written as a decimal is \(0.064\).
