Rate and Ratios IF 3 kg of potatoes cost R24. How much will 7 kg of potatoes cost ​
balu736 [363]

Answer:

7kg of potatoes cost 56 R (dollars)

Step-by-step explanation:

Now, all we have to do is multiply <u><em>8 by 7</em></u>.

8 is the unit rate/kg and 7kg is the amount they are asking.

<u><em>8x7=56</em></u>

7kg of potatoes cost 56R
