Q: In 12 453, the digit 4 is in the ________ place.

C. hundreds. In 12 453, reading from the right: 3 is ones, 5 is tens, 4 is hundreds, 2 is thousands, 1 is ten thousands. So the digit 4 is in the hundreds place.

Q: In which of the following are the numbers arranged from the greatest to the smallest? (greatest) ... (smallest)

B. 9680 , 9608 , 9068. Comparing 9068, 9608 and 9680: thousands all equal (9). Hundreds: 9680 has 6, 9608 has 6, 9068 has 0. So 9068 is smallest. Between 9680 and 9608, tens digits are 8 and 0 respectively, so 9680 > 9608. Greatest to smallest: 9680, 9608, 9068.

Q: Which of the following is a multiple of 9?

D. 81. Multiples of 9 are 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, ... 81 = 9 × 9, so 81 is a multiple of 9. 19, 39 and 3 are not multiples of 9.

Q: Linda had 112 bags. She packed 45 markers in each bag. How many markers were there altogether?

C. 5040. Total markers = 112 × 45 = 112 × 45 = 5040.

Q: Look at the diagram below. What is the size of ∠ABC?

A. 75°. Using the protractor, ray BC lies along the 0° baseline on the right, and ray BA goes up-left. Reading from the inner scale starting at C (0°) and moving anti-clockwise to A gives 75°.

Q: Judy baked 10 chocolate and 15 peanut cookies. She packed all the cookies into equal number of boxes. How many chocolate and peanut cookies were there in each box?

A. Chocolate 2, Peanut 3. The greatest common factor of 10 and 15 is 5, so there are 5 boxes. Chocolate per box = 10 ÷ 5 = 2; Peanut per box = 15 ÷ 5 = 3.

Q: Siti bought 369 oranges. She packed the oranges equally into bags of 4. What is the least number of bags of oranges she should buy?

D. 93. 369 ÷ 4 = 92 remainder 1. To pack ALL 369 oranges equally into bags of 4 she needs to top up to the next multiple of 4: 93 × 4 = 372 oranges, so she should buy enough for 93 bags (the least number of bags such that the oranges fit equally is 93).

Q: A table with 5 columns is filled with numbers in a certain pattern. The first 3 rows of the table are shown. In which column will the number 23 appear in?

C. C. Numbers fill 5 per row left-to-right: Row 1: 1-5, Row 2: 6-10, Row 3: 11-15, Row 4: 16-20, Row 5: 21-25. So 21 is Column A, 22 is Column B, 23 is Column C.

Q: After making a 3/4-turn in an anti-clockwise direction, Andy is standing at point X and facing the playground. Where was he facing at first?

B. Shop. Andy now faces the Playground (south-west direction from X). A 3/4 anti-clockwise turn equals a 1/4 clockwise turn. Reversing his motion (turning 3/4 clockwise OR 1/4 anti-clockwise to undo) — he originally faced 1/4 turn clockwise from Playground, which is the Shop (south-east direction).

Q: Peter folded 1000 paper cranes. He folded 4 times as many cranes as Alicia. How many paper cranes must Peter give to Alicia so that they each have the same number of cranes?

A. 375. Peter = 1000 (which is 4 units), so 1 unit = 250 → Alicia = 250 cranes. Total = 1250. Each should have 625. Peter must give 1000 − 625 = 375 cranes to Alicia.
