the options are missing, so I looked for a similar question (see attached image):
option B option DExplanation:
the equivalent ratios for pie crust and water are:
²/₃ : 3 (normal recipe)
⁴/₃ : 6 (double recipe)
if we equal both ratios:
²/₃ : 3 = ⁴/₃ : 6 we get option B (²/₃ / 3 = ⁴/₃ / 6)
if we reciprocate both sides (we basically flip them), then:
3 : ²/₃ = 6 : ⁴/₃, we get option D (3 / ²/₃ = 6 / ⁴/₃)
