Multiplication Practice Question 1

Nancy went to the aquatic centre. She swam 5 laps in the outdoor 50-metre pool before she felt cold and went inside to swim 4 laps in the 25-metre pool. How far did she swim in total?

A) 250 m

B) 350 m

C) 450 m

D) 100 m

 

Solution:

The correct answer is B) 350 m.

In the 50-metre pool, Nancy swam 5 laps, which is a distance of:

\(50 \times 5 = 250 \text{ m}\)

 

In the 25-metre pool, Nancy swam 4 laps, which is a distance of:

\(25 \times 4 = 100 \text{ m}\)

 

So, in total, Nancy swam:

\(250+100 = 350 \text{ m}\)

Multiplication Practice Question 2

When Tiffany arrives at school in the morning, she realises that she left her homework at home. Her mum drives back home to get her homework and then drops it off at school. After this whole morning fiasco, Tiffany’s mum finally drives back home to relax. If Tiffany’s house is 8 km from school, how far did her mum travel in total?

A) 24 km

B) 28 km

C) 30 km

D) 32 km

 

Solution:

The correct answer is D) 32 km.

Let’s list out every time when Tiffany’s mum made a trip to/from school:

1. Drive to school
2. Return home to get the homework
3. Drive to school again
4. Return back home

So, Tiffany’s mum drove between school and home 4 times in total. There is 8 km between school and home.

That means that Tiffany’s mum drove a total distance of:

\(8 \times 4 = 32 \text{ km}\)

 

Multiplication Practice Question 3

Tracey lays out her money, as shown below.

How much money does Tracey have?

A) $3.00

B) $1.50

C) $1.80

D) $2.00

 

Solution:

The correct answer is D) $2.00.

There are:

• 2 x 50¢ = 100¢ = $1.00
• 4 x 20¢ = 80¢ = $0.80
• 2 x 10¢ = 20¢ = $0.20

So, Tracey has a total of:

\(1.00 + 0.80 + 0.20 = $2.00\)

 

Multiplication Practice Question 4

Jerry is trying to figure out how many pastries he needs to bake for his party. He has invited 13 guests, and he wants to make 3 pastries for each person in attendance, including himself. Hence, how many pastries does Jerry need?

A) 42

B) 39

C) 44

D) 40

 

Solution:

The correct answer is A) 42.

There will be a total of 14 people at Jerry’s party (13 guests plus himself).

To provide each of the 14 people with 3 pastries, Jerry will need to make:

\(14 \times 3 = 42 \text{ pastries}\)

 

Multiplication Practice Question 5

Anne likes to cut her square sandwiches into two equally-sized triangles. The diagram below shows what this looks like.

What is the area of a triangular slice?

A) 16 cm²

B) 30 cm²

C) 32 cm²

D) 64 cm²

 

Solution:

The correct answer is C) 32 cm².

The area of the triangle:

\begin{align*}
\frac{1}{2} \times 8 \times 8 &= \frac{1}{2} \times 64 \\
&= 32 \text{ cm}^2 \\
\end{align*}

 

Multiplication Practice Question 6

New carpet is to be laid out in a library. It is to be laid out over the whole floor, except where there are shelves. The library covers an area of 35 m² and each shelf covers 5 m². If there are three shelves (as shown in the arrangement below), how many square metres of carpet are required?

 

A) 20 m²

B) 25 m²

C) 30 m²

D) 35 m²

 

Solution:

The correct answer is A) 20 m².

Area of carpet required:

\begin{align*}
35 – 5 \times 3 &= 35 – 15 \\
&= 20 \text{ m}^2 \\
\end{align*}

 

Multiplication Practice Question 7

At the aquarium, Gilbert sees a big tank. The dimensions are shown below:

What is the volume of the tank?

A) 20 m³

B) 27 m³

D) 30 m³

 

Solution:

The correct answer is D) 30 m³.

Volume of the tank:

\begin{align*}
3 \times 5 \times 2 &= 15 \times 2\\
&= 30 \text{ m}^3\\
\end{align*}

By referring to the diagram, we can conclude that the total number of possible outfit combinations is:

\begin{align*}
3 \times 7 \times 5 \times 2 &= (3 \times 7) \times (5 \times 2) \\
&= 21 \times 10 \\
&= 210 \\
\end{align*}
