Estimating Quotients with Rounding

The video tutorial teaches how to estimate decimal quotients using two methods: rounding and compatible numbers. The rounding method involves adjusting numbers to the nearest whole number based on specific rules, while the compatible numbers method uses numbers close to the original for easier division. Examples are provided for both methods to illustrate the process.
