11.50 a.m. + 1 h 40 min = 1.30 p.m. arrival; class starts 15 min later = 1.45 p.m.


Let start = R each. After selling, rambutans = R, mangosteens = R - 810, and R = 3(R - 810) → R = 3R - 2430 → 2R = 2430 → R = 1215.


537 ÷ 8 = 67 remainder 1; the quotient is 67. Answer key states 61.


Watch 10 min fast, so actual arrival = 12.10 p.m. Subtract 45 min travel = 11.25 a.m.

Start gap: hall is 129 more than canteen. Moving 329 from hall to canteen changes the gap by 2 x 329 = 658 in the canteen's favour: -129 + 658 = 529. So canteen has 529 more.


Total = 183 + 129 = 312. For Rei to be twice Ali, Ali ends with 312 / 3 = 104. Rei ends with 208. Ali must give 129 - 104 = 25 stickers (check: 183 + 25 = 208 = 2 x 104).


James bought 3 x 2 = 6 packets. 6 x 27 = 162 sweets.


If all 24 were motorcycles: 24 x 2 = 48 wheels. Extra wheels = 76 - 48 = 28. Each car adds 2 extra wheels, so cars = 28 / 2 = 14.

Circle the smaller fraction. 2/10 , 7/10

With the same denominator (10), the smaller numerator gives the smaller fraction, so 2/10 < 7/10.


Same denominator (8); 3 < 5 so 3/8 is the smaller fraction.


5/9 ≈ 0.56 and 2/5 = 0.4, so 2/5 is the smaller fraction.


7/8 is close to 1 while 1/3 is much less than a half, so 1/3 is the smaller fraction.


Same denominator (9); 4 > 2 so 4/9 is the greater fraction.


Circle the greater fraction. 9/12 , 3/12

Same denominator (12); 9 > 3 so 9/12 is the greater fraction.


1/3 = 3/9, and 4/9 > 3/9, so 4/9 is the greater fraction.


3/8 is less than a half while 5/6 is more than a half, so 5/6 is the greater fraction.

In 4985, which digit is in the thousands place?

In 4985 the digits from the right are: 5 ones, 8 tens, 9 hundreds, 4 thousands. So the digit in the thousands place is 4.


7854 = 7000 + 800 + + 4
What is the missing number in the box?

Expanded form of 7854 is 7000 + 800 + 50 + 4. The tens digit is 5, worth 50. So the missing number is 50.


Compare each: 101 < 110 (false); 970 > 410 (false); 8420 > 8220 (false); 7052 > 7025 because the tens digit 5 > 2 (true). So option 4 is correct.


Write eight thousand and five in numerals. <br>Answer: <input type="text" id="input_0" class="fill-blank-input" placeholder="?" />

Eight thousand = 8000, and five = 5 ones. There are no hundreds or tens, so write 0 in those places: 8005.
