  4. Ka piki te rerekētanga mā te 5; ko te 31

Explanation

Ko ngā rerekētanga: 5−2=3, 10−5=5, 17−10=7, 26−17=9. Ka piki te rerekētanga mā te 2 ia wā, nō reira ko te rerekētanga e whai ake ko te 11, ā, ko te 26 + 11 = 37.

Question 47Pāngarau

E 3/8 o tētahi mahi kua oti i te ata, ā, e 1/4 kua oti i te ahiahi. E hia te wāhanga o te mahi e toe ana?

  1. 3/8 Correct answer.
  2. 5/8
  3. 1/8
  4. 1/2

Explanation

Me huri ngā hautau kia rite te tauraro: 3/8 me te 2/8 (nā te mea ko te 1/4 = 2/8). Ko te tapeke = 5/8, nō reira ko te toe = 8/8 − 5/8 = 3/8.

Question 48Pāngarau

Ko te horahanga o tētahi tapawhā hāngai ko te 48 cm², ā, ko tōna paenga ko te 28 cm. He aha te roa me te whānui?

  1. 8 cm me te 6 cm Correct answer.
  2. 12 cm me te 4 cm
  3. 24 cm me te 2 cm
  4. 16 cm me te 3 cm

Explanation

Me rapu ngā tau e rua e hua ana i te 48, ā, e hua ana i te 14 ina tāpirihia (nā te mea ko te paenga = 2 × (roa + whānui) = 28, nō reira ko te roa + whānui = 14). Ko te 8 me te 6: 8 × 6 = 48, ā, 8 + 6 = 14.

Question 49Pāngarau

Ko te 40% o ngā ākonga o tētahi rōpū e 24. Ko te 25% o ngā ākonga o tētahi atu rōpū e 15. He aha te rerekētanga o ngā tapeke o ngā rōpū e rua?

  1. 0 Correct answer.
  2. 9
  3. 24
  4. 6

Explanation

Ko te tapeke o te rōpū tuatahi = 24 ÷ 0.4 = 60. Ko te tapeke o te rōpū tuarua = 15 ÷ 0.25 = 60. Nō reira ko te rerekētanga = 60 − 60 = 0.

Question 50Pāngarau

Ka whakareatia tētahi tau ki te 4, kātahi ka tangohia te 9, ka puta te 39. He aha te tau?

  1. 14
  2. 12 Correct answer.
  3. 7.5
  4. 10

Explanation

Me mahi whakamuri: 39 + 9 = 48, kātahi 48 ÷ 4 = 12. Ka whakamātau: 12 × 4 − 9 = 39, he tika.
