SELECT THE CORRECT PROPORTION FOR THE FOLLOWING SCENARIO: A SUNFLOWER GROWS 8 FEET IN 92 DAYS, AT CONSTANT RATE. HOW COULD YOU USE THIS INFORMATION TO FIND THE NUMBER OF DAYS IT TOOK FOR THE SUNFLOWER TO GROW 6 FEET?

• $$\frac{92\ DAYS}{8\ FEET}=\frac{6\ FEET}{X}$$

• $$\frac{6\ FEET}{92\ DAYS}=\frac{8\ FEET}{X}$$

• $$\frac{8\ FEET}{92\ DAYS}=\frac{6\ FEET}{X}$$

• $$\frac{6\ FEET}{8\ FEET}=\frac{92\ DAYS}{X}$$

SIDE LENGTH(CM) 2 4 6

PERIMETER (CM) 8 16 24

1. ARE THE PERIMETER AND THE SIDE LENGTH OF SQUARES PROPORTIONAL? EXPLAIN

• THE RATIOS $$\frac{PERIMETER}{SIDE\ LENGTH}$$ FOR THE SQUARES ARE EQUIVALENT, SO THEY ARE PROPORTIONAL.

• THE RATIOS $$\frac{PERIMETER}{SIDE\ LENGTH}$$ FOR THE SQUARES ARE EQUIVALENT, SO THEY ARE NOT PROPORTIONAL.

• THERE IS NOT A PROPORTIONAL RELATIONSHIP BETWEEN X AND Y, BECAUSE X IS NOT A MULTIPLE OF Y SO THEY ARE NOT PROPORTIONAL.

• Y MUST BE DIVIDED INTO X, SO THEY ARE NOT PROPORTIONAL.

Multiple Choice

(QUESTION 2)

CHOOSE THE CORRECT PROPORTION AND ITS VALUE THAT FINDS THE PERIMETER OF A SQUARE WHEN ITS SIDE LENGTH IS 12 CM.

• $$\frac{.25}{1}=\frac{12}{P}$$

• $$\frac{4}{1}=\frac{P}{12}\ =36\ CM$$

• $$\frac{1}{4}=\frac{P}{12}=48\ CM$$

• $$\frac{4}{1}=\frac{P}{12}=48\ CM$$
