Key notes:<\/p>\n\n\n\n

\ud83d\udd39 What is a Unit Rate?<\/h3>\n\n\n\n

\ud83d\udc49 A unit rate<\/strong> is a rate where the second quantity is 1<\/strong>.
\ud83d\udccc It helps us compare things easily.<\/p>\n\n\n\n

\ud83e\uddc3 Example:
If \u20b960 for 3 juices<\/strong>,
\u27a1\ufe0f Unit rate = \u20b960 \u00f7 3 = \u20b920 per juice<\/strong><\/p>\n\n\n\n

\n\n\n\n

\ud83d\udd39 Why Do We Use Unit Rates? \ud83e\udd14<\/h3>\n\n\n\n

\u2705 To compare prices \ud83d\uded2
\u2705 To find speed \ud83d\ude97
\u2705 To check value for money \ud83d\udcb0
\u2705 To make quick decisions \ud83d\udc4d<\/p>\n\n\n\n

\n\n\n\n

\ud83d\udd39 How to Find a Unit Rate \ud83e\uddee<\/h3>\n\n\n\n

1\ufe0f\u20e3 Write the rate as a fraction
2\ufe0f\u20e3 Divide the numerator by the denominator<\/strong>
3\ufe0f\u20e3 Make the denominator 1<\/strong><\/p>\n\n\n\n

\u270f\ufe0f Example:
120 km in 3 hours
\u27a1\ufe0f 120 \u00f7 3 = 40 km per hour<\/strong> \ud83d\ude98<\/p>\n\n\n\n

\n\n\n\n

\ud83d\udd39 Common Unit Rates \ud83d\udcca<\/h3>\n\n\n\n

\ud83d\udccc Speed \u2192 km per hour (km\/h)
\ud83d\udccc Cost \u2192 rupees per item (\u20b9\/item)
\ud83d\udccc Wages \u2192 rupees per hour (\u20b9\/hr)
\ud83d\udccc Density \u2192 people per km\u00b2<\/p>\n\n\n\n

\ud83d\udd39 Comparing Using Unit Rates \u2696\ufe0f<\/h3>\n\n\n\n

\ud83d\udc49 Find unit rates first, then compare.<\/p>\n\n\n\n

\ud83d\udecd\ufe0f Example:
\u2022 Pack A: \u20b9100 for 4 pens \u2192 \u20b925 per pen
\u2022 Pack B: \u20b9120 for 6 pens \u2192 \u20b920 per pen
\u2705 Pack B is cheaper!<\/strong> \ud83c\udf89<\/p>\n\n\n\n

\ud83d\udd39 Real-Life Examples \ud83c\udf0d<\/h3>\n\n\n\n

\ud83c\udf55 Price per slice
\ud83d\ude95 Fare per kilometer
\ud83d\udcf1 Data cost per GB
\u26a1 Electricity cost per unit<\/p>\n\n\n\n

\n\n\n\n

\ud83d\udd39 Important Tips \u2b50<\/h3>\n\n\n\n

\u2714\ufe0f Always check the units<\/strong>
\u2714\ufe0f Divide carefully
\u2714\ufe0f Bigger unit rate doesn\u2019t always mean better value
\u2714\ufe0f Use unit rates to compare fairly<\/p>\n\n\n\n

\ud83c\udfaf Quick Reminder!<\/h3>\n\n\n\n

\ud83d\udce2 Unit Rate = Total Quantity \u00f7 Number of Units<\/strong><\/p>\n\n\n\n

\n

Learn with an example<\/strong><\/p>\n\n\n\n
