15. Students plant 148 flowers at a community park. Seventy-eight percent of the flowers are pansies. Use rounding to estimate how many flowers are pansies.

To estimate how many flowers are pansies, you can round 148 to a simpler number, like 150. Then, to find 78% of that rounded figure, you can roughly calculate 78% of 150. Since 1% of 150 is 1.5, you can multiply 78 by 1.5 to get about 117. So, by rounding, you'd estimate that there are roughly 117 pansies in the community park. This method can be very handy not just in math, but in everyday life! When you go grocery shopping, estimating prices can help you stay within your budget without needing a calculator. Rounding allows for quicker calculations, especially when you're short on time or have many items to consider!
