Explanation:

Part 1: Classify Expressions and Equations

Step1: Identify expressions (no = sign)

Expressions: $\frac{2}{3} \div \frac{1}{7}$, $0.25g \times 0.76h$, $(6 + 9) \times 4$, $\frac{3 + 2j}{10}$

Step2: Identify equations (has = sign)

Equations: $6 + k = 14$, $10^4 = 5z$, $8w - 3w = 20$, $3 = (2p + 7) \div 5$, $2m + 7n = 14n - 1$

Step1: Analyze $10x - y + 3.5$

• Terms: Separated by $+/-$: $10x$, $-y$, $3.5$ → 3 terms
• Coefficient of first term: Number with $x$ → 10
• Constant term: Number without variable → 3.5

Step2: Analyze $3a + 6 + b$

• Terms: Separated by $+/-$: $3a$, $6$, $b$ → 3 terms
• Variables: Letters representing unknowns → $a$, $b$
• Factors of $3a$: Numbers/terms multiplied → 3, $a$

Answer:

• Circled (Expressions): $\frac{2}{3} \div \frac{1}{7}$, $0.25g \times 0.76h$, $(6 + 9) \times 4$, $\frac{3 + 2j}{10}$
• Boxed (Equations): $6 + k = 14$, $10^4 = 5z$, $8w - 3w = 20$, $3 = (2p + 7) \div 5$, $2m + 7n = 14n - 1$
