## Answers:

1- **C**

The question is that number \(56,743.21\) is how many times number \(5.674321\). The answer is \(10,000\).

2- **C **

Lily eats \(2\) pancakes in \(1\) minutes ⇒ , Lily, eats \(2×5\) pancakes in \(5\) minutes.

Ella eats \(2\frac{1}{2}\) pancakes in \(1\) minute ⇒ Ella eats (2\frac{1}{2}\) \(× 5\) pancakes in \(5\) minutes.

In total Lily and Ella eat \(10 + 12.5 \)pancakes in \(5\) minutes.

3- **B **

Alice drives \(68\) miles in one hour. Therefore, she drives \(2600\) miles in about \((2600 ÷ 68) 38\) hours.

4- **C**

\(12\) yards \(= 12 × 36 = 432\) inches

\(4\) feet \(= 4 × 12 = 48\) inches

\(12\) yards \(4\) feet and \(2\) inches \(= 432\) inches \(+ 48\) inches \(+ 2\) inches\( = 482\) inches

5- **A**

Simplify each option provided using order of operations rules.

\(8 – (–2)+ (–18)=8+2-18=-8 \)

\( 2+(–3)×(–2)=2+6=8\)

\( –6×(–6)+ (–2)×(–12)=36+24=60\)

\( (–2)×(–7)+4=14+4=18\)

6- **C**

To find the answer, subtract \(40,907\) from \(41,053\).

\(41,053-40,907=146 \space\) miles

7- **A**

\( \frac{5}{8}× \frac{4}{5}=\frac{5×4}{8×5}=\frac{20}{40}=\frac{1}{2}\)

8- **3360**

Use volume of cube formula.

\( Volume= base × height ⇒ V= 120 × 28 ⇒ V=3,360\)

9- **B**

\(1\) pizza has \(8\) slices.

\(18\) pizzas contain \((18 × 8) 144\) slices.

10- **B**

Use area of rectangle formula.

\(Area= length × width ⇒ A=\frac{3}{4} × \frac{5}{6} ⇒ A=\frac{5}{8}\space inches\)
