Below is a step‐by‐step solution to each part of the problem: ──────────────────── 1. (Question 4a) ──────────────────── • Question: How many whole numbers are there from –5 to 0? • Interpretation: Although “whole numbers” are sometimes defined as the nonnegative integers (0, 1, 2, …), in many contexts “whole numbers” means “integers” on a number line. Since –5 is negative, here we count every integer from –5 up to 0. • List the numbers: –5, –4, –3, –2, –1, 0. • Count: There are 6 numbers. Answer for 4a: 6 ──────────────────── 2. (Question 5) ──────────────────── • Question: What are the values of these digits in the number 1,456,709? – a) the digit 7 – b) the digit 4 Step 1. Write the number with its place values:   1  4  5  6  7  0  9   |  |  |  |  |  |  |   M HTh TTh Th H  T  O   (million, hundred‑thousands, ten‑thousands, thousands, hundreds, tens, ones) a) For the digit 7:  – Its position is the hundreds place.  – Value: 7 × 100 = 700. b) For the digit 4:  – Its position is the hundred‑thousands place.  – Value: 4 × 100,000 = 400,000. Answer for 5a: 700 Answer for 5b: 400,000 ──────────────────── 3. (Question 6) ──────────────────── • Write these names as single numbers. a) “three billion, five million, four hundred and sixty‑eight thousand and ten”  – Break it down:   • Three billion = 3,000,000,000   • Five million = 5,000,000   • Four hundred and sixty‑eight thousand = 468,000   • And ten = 10  – Add them together:   3,000,000,000 + 5,000,000 = 3,005,000,000   3,005,000,000 + 468,000 = 3,005,468,000   3,005,468,000 + 10 = 3,005,468,010 Answer for 6a: 3,005,468,010 b) “sixty million, five hundred and four thousand and forty‑two”  – Break it down:   • Sixty million = 60,000,000   • Five hundred and four thousand = 504,000   • And forty‑two = 42  – Add them together:   60,000,000 + 504,000 = 60,504,000   60,504,000 + 42 = 60,504,042 Answer for 6b: 60,504,042 ──────────────────── 4. (Question 7) ──────────────────── • Use a number line to show each number you land on after starting at the given point and moving the specified number of spaces. a) Start on 2, and move 3 spaces in a negative direction.  • Calculation: 2 – 3 = –1  • On the number line, you start at 2 and then step left three units to land at –1.   b) Start on –5, and move 6 spaces in a positive direction.  • Calculation: –5 + 6 = 1  • On the number line, you start at –5 and then step right six units to land at 1.   c) Start on –6, and move 5 spaces in a negative direction.  • Calculation: –6 – 5 = –11  • On the number line, start at –6 and then step left five units to end at –11. ──────────────────── Summary of Answers: ──────────────────── 4a) 6 whole numbers. 5a) The digit 7 represents 700. 5b) The digit 4 represents 400,000. 6a) 3,005,468,010 6b) 60,504,042 7a) You land on –1. 7b) You land on 1. 7c) You land on –11. These complete the solutions to the given problems.
