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

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

Answer 2

In order to do this we must see if
$\frac{20}{2}= \frac{35}{3.5} ?$

$\frac{20}{2} = 10$

$\frac{35}{3.5} = \frac{35}{ \frac{7}{2} } = \frac{5*2*7}{7} = 10$

$10 = 10$ √
