Ratios, Proportions, Unit rates, percents - Coggle Diagram

- - - - Example: If three shirts cost 300 Rand we can say that: Rands compared to Shirts
        
        R300 to 3 shirts
        
        R300 : 3 Shirts
        
        R3003 Shirts This is the one that we will use most.
        
        Like fractions, these can be reduced just as the same by using division. They can also be manipulated to create and look at different comparisons, same as finding equivalent fractions.
        
        Reducing: R30033 Shirts3=R1001 shirt
        
        How much do 6 shirts cost? R300(2)3 Shirts(2)=R6006 shirts or R30033 Shirts3=R100(6)1 shirt(6)=R6006 shirts
        
        There are many real-world situations in which something keeps happening at the same rate. For example:
        
        a bus stop that is serviced by 4 buses per hour
        
        a washing machine that takes 45 minutes per load of laundry
        
        a school cafeteria that serves 15 students per minute
        
        In situations like these, we can use equivalent ratios to predict how long it will take for something to happen some number of times, or how many times it will happen in a particular length of time.
        
        How long will it take the school cafeteria to serve 600 students?
        
        The table shows that it will take the cafeteria 40 minutes to serve 600 students.
        
        How many students can the cafeteria serve in 1 hour?
        
        The double number line shows that the cafeteria can serve 900 students in 1 hour.

    - - Ratios are a comparison of two values, ideas, or quantities. They can be written a couple of different ways.
