Viswanath mixed 6 cups of rice with 3 cups of urad dal to make idlis, while Puneet mixed 4 cups of rice with 2 cups of urad dal. If cooked in the same way, would their idlis taste the same?
  • Yes, because the ratios 6:3 and 4:2 are proportional
  • No, because the ratio of rice to urad dal is different in the two mixtures
  • Yes, because both mixtures use more rice than urad dal, regardless of ratio
  • No, because Puneet used fewer total cups than Viswanath

If you measure the same two cities on different maps that use different scales (ratios), what should be true about the geographical distance you compute from each map?
  • It should be approximately the same after converting with each map’s scale
  • It will be exactly the same map length on every map
  • It will vary widely because different scales always give different real distances
  • It cannot be determined without knowing road distances

Construct a triangle with side lengths in the ratio 3 : 4 : 5. Will all triangles drawn with this ratio of side lengths be congruent to each other? Choose the best answer.
  • No. Triangles with side lengths in the same ratio are similar; they are congruent only if the actual side lengths are equal.
  • Yes. Any triangles with sides in the ratio 3 : 4 : 5 are always congruent.
  • Yes. All triangles with equal angles are automatically congruent.
  • No. Such triangles are neither similar nor congruent.
Can you construct a triangle with side lengths in the ratio 1 : 3 : 5? Choose the best answer.
  • No. The sum of the two shorter sides is less than the longest side, so a triangle cannot be formed.
  • Yes. Any three positive lengths in a ratio can form a triangle.
  • Yes, but only a right triangle can be formed with this ratio.
  • No. The perimeter would be too large to construct with a ruler.
For the pie chart of grade distribution where the number of students scoring grades A, B, C, D, E are 12, 10, 8, 6, 4 respectively (total angle around a circle is 360°), how should the slices be marked?
  • The angle for each grade should be proportional to the number of students with that grade.
  • Each grade should be marked with equal angles since all are grades.
  • The largest grade should be assigned 180° and the rest split equally.
  • The slice angles should be chosen arbitrarily as long as they add to 360°.
For the ratio of students scoring grades A : B : C : D : E = 12 : 10 : 8 : 6 : 4 in a pie chart, can this ratio be reduced to its simplest form?
  • Yes, it reduces to 6 : 5 : 4 : 3 : 2.
  • No, it is already in simplest form.
  • Yes, it reduces to 12 : 10 : 8 : 6 : 4.
  • Yes, it reduces to 3 : 2 : 2 : 1 : 1.
