Question

Number 4? What would you do?

Answer 1

We Have Two Rates To See if Are Equivalent$\frac{12\ minutes}{30\ laps}\ and\ \frac{48\ minutes}{120\ laps} \\ We\ Need\ To\ Simplify.\\ Divide\ Everything\ By\ 6.\\ (12/30)/(6/6) = (2/5) \\ (48/120)/(6/6) = (8/20)/4/4 = 2/5\\ Is\ 2/5\ And\ 2/5\ The\ Same?$:
Yes! So, 12 minutes/30 laps is the same as 48 minutes/120 laps.

Answer 2

i think that 4 is proportionate
12/30 = 48/120
i think the proportion is 4/3
