Here are the solutions to the math problems.

Question 2.3 Step 1: Determine the total number of parts in the ratio. Total parts $= 3 + 2 = 5$

Step 2: Calculate the number of learners per part. Learners per part $= \frac{Total learners}{Total parts} = \frac{125}{5} = 25$ learners

Step 3: Calculate the number of learners who jog. Number of joggers $= 3 \times 25 = 75$ learners

Step 4: Calculate the number of learners who cycle. Number of cyclists $= 2 \times 25 = 50$ learners

$\boxed{Joggers: 75 learners, Cyclists: 50 learners}$

Question 2 (Tractor problem) Step 1: Calculate the amount to be financed after the deposit. Loan principal $(P) = Tractor price - \text{Deposit}$ $P = R160\,000 - R20\,000 = R140\,000$

Step 2: Convert the loan period from months to years. Time $(t) = \frac{60 months}{12 months/year} = 5 \text{ years}$

Step 3: Calculate the simple interest. Simple Interest $(I) = P \times r \times t$ $I = R140\,000 \times 0.10 \times 5$ $I = R70\,000$

Step 4: Calculate the total amount paid for the loan (principal + interest). Amount to repay $= P + I$ $Amount to repay = R140\,000 + R70\,000 = R210\,000$

Step 5: Calculate the total amount paid, including the deposit. Total amount paid $= Deposit + \text{Amount to repay}$ $Total amount paid = R20\,000 + R210\,000 = R230\,000$

$\boxed{R230\,000}$

Question 3.1.1 Step 1: Calculate the product of $-4$ and $3$. Product $= (-4) \times 3 = -12$

Step 2: Calculate the sum of $-4$ and $3$. Sum $= (-4) + 3 = -1$

Step 3: Subtract the product from the sum. Result $= Sum - \text{Product}$ $Result = (-1) - (-12)$ $Result = -1 + 12$ $Result = 11$

$\boxed{11}$

Question 3.1.2 Step 1: Convert the fraction to a decimal. $\frac{5}{8} = 0.625$

Step 2: Multiply the decimal by $100\%$ to express it as a percentage. $0.625 \times 100\% = 62.5\%$

$\boxed{62.5\%}$

Question 3.1.3 Step 1: Set up the given equation. $\frac{3}{7} = \frac{12}{A}$

Step 2: Cross-multiply to solve for $A$. $3 \times A = 7 \times 12$ $3A = 84$

Step 3: Divide by $3$ to find the value of $A$. $A = \frac{84}{3}$ $A = 28$

$\boxed{28}$
