Question

Sherlock put two tomato plants in his garden. The first tomato plant produced 20 tomatoes in a 2-day period. The second tomato plant produced 35 tomatoes in a 3.5-day period. Are these rates proportional? Explain why or why not.

Answer 1

In order to do this we must see if

`(20)/(2)= (35)/(3.5) ?`


`(20)/(2) = 10`


`(35)/(3.5) = (35)/( (7)/(2) ) = (5*2*7)/(7) = 10`


`10 = 10` √

Answer 2

rate=progress/time
progress=number of tomatoes

are rates the same aka are they equal?
20/2=35/3.5?
10=35/3.5
10=70/7
10=10
true

yes they are
