👉 In mathematics, a denominator is defined as the bottom number in a fraction. It represents how many equal parts are being divided into one whole. In other words, it's like the number of pieces you're splitting up to make your cake or pizza. For example, if you have 3 parts in a cake with each part having 4 slices, then 1/3 would represent the denominator as it represents how many equal parts are being divided into one whole.
