1. What is the value of the digit 8 in 581 340?

Answer:

📖 REMINDER: Identify the position of the digit in the 6-digit number. Count from the right: ones, tens, hundreds, thousands, ten-thousands, hundred-thousands.

2. Find the value of 96 000 ÷ 400.

Answer:

📖 REMINDER: Divide both numbers by 100 first to simplify, then divide the remaining values.

3. Find the value of 5 − ³⁄₈.

Answer:

📖 REMINDER: Rewrite the whole number as a mixed number to make subtraction easier: 5 = 4⁸⁄₈, then subtract the fraction.

4. Round 73 648 to the nearest thousand.

Answer:

📖 REMINDER: Look at the hundreds digit. If it is 5 or more, round up the thousands digit. If it is less than 5, round down (keep the thousands digit the same). Replace the hundreds, tens and ones with zeros.

5. Find the value of ⁵⁄₆ × 54.

Answer:

📖 REMINDER: Divide the whole number by the denominator first, then multiply by the numerator.

6. What is the value of 35 + (63 − 9 × 5) ÷ 6?

Answer:

📖 REMINDER: Follow BODMAS — inside the bracket, do multiplication first, then subtraction. Then divide the bracket result. Finally add.

7. 10 ℓ of syrup was poured equally into 15 bottles. How much syrup was poured into each bottle?
Give your answer as a fraction in its simplest form.

Answer:   ℓ

📖 REMINDER: Divide the total amount by the number of bottles to get a fraction, then simplify by dividing numerator and denominator by their HCF.

8. Express ³⁄₇ as a decimal correct to 2 decimal places.

Answer:

📖 REMINDER: Divide 3 by 7 using long division to at least 3 decimal places, then round to 2 decimal places.

9. Rajan had ³⁄₄ kg of flour. He used ²⁄₉ of it to bake some bread. What was the mass of flour that he used?
Give your answer as a fraction in its simplest form.

Answer:   kg

📖 REMINDER: Multiply the total quantity by the fraction used. Simplify the resulting fraction by dividing by the HCF.

10. Mr Wong baked 630 pies. He sold 98 pies in the morning and ³⁄₇ of the pies in the afternoon.
How many pies did he sell altogether?

Answer:   pies

📖 REMINDER: Find the number of pies sold in the afternoon first (fraction × total), then add to the morning amount.

11. Mrs Chow spent ³⁄₇ of her salary on rent and ²⁄₅ of the remainder on food. She then saved the rest of
her salary. Mrs Chow spent $90 more on rent than the amount she saved. How much was Mrs Chow's salary?

Answer: $ 

📖 REMINDER: Express rent, food and savings all as fractions of the total salary. Then use the difference between rent and savings to find 1 unit, and scale up to the full salary.

12. Kai, Lin and Ming had some money. Kai and Lin had $3850. Lin and Ming had $7130.
Ming had 5 times as much money as Kai. How much money did Lin have?

Answer: $ 

📖 REMINDER: Use the "5 times" relationship to find the difference between Ming and Kai. Match this to the difference in the two pair-totals to find Kai's amount, then subtract from the first pair.

13. There were 1440 fish in Tank A. Tank A had 480 more fish than Tank B. Some fish were moved
from Tank A to Tank B.Tank B then had 3 times as many fish as Tank A. How many fish were
moved from Tank A to Tank B?

Answer:   fishes

📖 REMINDER: Find Tank B's original amount, then the total in both tanks. After moving, B = 3A and A + B = same total. Solve for A (after), then find how many were moved.
