Question

directions: draw a circle around each expression. draw a rectangle around each equation.
6 + k = 14
\frac { 2 } { 3 } div \frac { 1 } { 7 }
0.25g × 0.76h
10^{2}=5z
8w - 3w = 20
3 = (2p + 7) ÷ 5
(6 + 9) × 4
2m + 7n = 14n - 1
\frac { 3 + 2j } { 10 }

Explanation:

Step1: Identify equations

Equations have an equal sign.

• \(6 + k=14\) has an equal sign.
• \(10^{2}=5z\) has an equal sign.
• \(8w - 3w=20\) has an equal sign.
• \(3=(2p + 7)\div5\) has an equal sign.
• \(2m+7n = 14n-1\) has an equal sign.

Step2: Identify expressions

Expressions do not have an equal sign.

• \(\frac{2}{3}\div\frac{1}{7}\) has no equal sign.
• \(0.25g\times0.76h\) has no equal sign.
• \((6 + 9)\times4\) has no equal sign.
• \(\frac{3 + 2j}{10}\) has no equal sign.

Answer:

• Equations (draw rectangle around): \(6 + k=14\), \(10^{2}=5z\), \(8w - 3w=20\), \(3=(2p + 7)\div5\), \(2m+7n = 14n-1\)
• Expressions (draw circle around): \(\frac{2}{3}\div\frac{1}{7}\), \(0.25g\times0.76h\), \((6 + 9)\times4\), \(\frac{3 + 2j}{10}\)
