Understanding Percent of a Number

The video tutorial from MooMooMath and Science teaches how to solve percent of a number problems using a mnemonic device: replace, move, and solve. The instructor demonstrates this method with two example problems involving fractional percentages. The process involves converting percentages to decimals, replacing 'of' with multiplication, and solving the resulting equation. The video concludes with a recap and an invitation to subscribe for more math and science content.
