b) \( \frac{90}{30}= \)

Did you know that the concept of division has been around for thousands of years? Ancient civilizations like the Babylonians and Egyptians used division in their calculations, helping pave the way for modern mathematics! The simple act of dividing numbers allowed them to trade, measure land, and even build pyramids. To solve \( \frac{90}{30} \), simply think of how many times 30 fits into 90. You can break it down: 30 fits into 90 exactly three times (because \( 30 \times 3 = 90 \)). So, the answer is 3! Just remember, when in doubt, breaking it down into smaller parts can make division easier.
