Google charges me for the hosting of this website and my other
educational websites. It does not host any of the websites for free.
Besides, I spend a lot of time to type the questions and the solutions well.
As you probably know, I provide clear explanations on the solutions.
Your donation is appreciated.
Comments, ideas, areas of improvement, questions, and constructive
criticisms are welcome.
Feel free to contact me. Please be positive in your message.
I wish you the best.
Thank you.
(1.) Work out 50 ÷ 5
50 ÷ 5 = 10
(2.) Simplify this fraction to its lowest terms: $\dfrac{16}{56}$
(13.) A triathlon race consists of a swim, a run and a bicycle ride.
The swim is $\dfrac{1}{8}$ of the total distance.
The run is $\dfrac{2}{5}$ of the total distance.
What fraction of the total distance do the swim and run cover altogether?
$
\text{Let the total distance} = d \\[3ex]
swim = \dfrac{1}{8}d \\[5ex]
run = \dfrac{2}{5}d \\[5ex]
swim + run \\[3ex]
= \dfrac{d}{8} + \dfrac{2d}{5} \\[5ex]
= \dfrac{5d + 16d}{40} \\[5ex]
= \dfrac{21d}{40} \\[5ex]
$
The fraction of the total distance that the swim and run cover altogether is $\dfrac{21}{40}$
(17.) Put a mark (✓) next to the regular quadrilateral.
Shape
parallelogram
rhombus
square
rectangle
A Regular Polygon is a polygon that is equilateral (equal sides) and equiangular (congruent
angles).
The square has equal sides and congruent angles.
The regular quadrilateral in the table is the square.
(18.) Which fraction is equal to 20%?
$
\dfrac{1}{6} ~~~~~~~ or ~~~~~~~ \dfrac{1}{20} ~~~~~~~ or ~~~~~~~ \dfrac{1}{5} \\[5ex]
$
$
\dfrac{1}{5} = \dfrac{1}{5} * 100\% = 20\%
$
(19.) The area of this circle is 60 cm².
What is the area of the shaded part?
The shaded area is one–quarter of the area of the circle.
(20.) There is $\dfrac{1}{4}$ of a cake left over in the fridge.
It is shared equally among Anne, Bill and Carl.
What fraction of the whole cake does Anne get?
$
\text{Let the entire cake} = c \\[3ex]
Left\;\;over = \dfrac{1}{4}c \\[5ex]
\text{Shared equally among 3 people} \\[3ex]
\text{Each person gets:} \dfrac{1}{4}c \div 3 \\[5ex]
= \dfrac{1}{4}c * \dfrac{1}{3} \\[5ex]
= \dfrac{1}{12}c \\[5ex]
$
Anna gets $\dfrac{1}{12}$ of the whole cake.
