Stage 6 - Worked example
There are some small cubes and some large cubes in a bag. The cubes are red or the cubes are yellow.
The ratio of the number of small cubes to the number of large cubes is 4 : 7
The ratio of the number of red cubes to the number of yellow cubes is 3 : 5
(a) Explain why the least possible number of cubes in the bag is 88
All the small cubes are yellow.
(b) Work out the least possible number of large yellow cubes in the bag.
Stage 6 - Questions
30) There are some small cubes and some large cubes in a bag. The cubes are red or the cubes are yellow.
The ratio of the number of small cubes to the number of large cubes is 3 : 7
The ratio of the number of red cubes to the number of yellow cubes is 2 : 1
(a) Explain why the least possible number of cubes in the bag is 30
All the small cubes are yellow.
(b) Work out the least possible number of large yellow cubes in the bag.
The least possible number of cubes has to be the lowest common multiple of
(4 + 7) and (3 + 5), i.e. the LCM of 11 and 8, which is 88.
The number of small cubes =88
11× 4 = 32 (divide the 88 cubes into the 4 : 7 ratio).
The number of yellow cubes =88
8× 5 = 55 (divide the 88 cubes into the 3 : 5 ratio).
Since all the small cubes are yellow:
The number of large yellow cubes
= number of
yellow cubes −
number of small yellow cubes
= 55 − 32
= 𝟐𝟑

Stage 7 - Worked example
A shop sells packs of black pens, packs of red pens and packs of green pens.
There are
2 pens in each pack of black pens
5 pens in each pack of red pens
6 pens in each pack of green pens
On Monday,
number of packs of black pens sold
: number of packs of red pens sold
: number of packs
of green pens sold = 7 : 3 : 4
A total of 212 pens were sold.
Work out the number of green pens sold.
Stage 7 - Questions
34) A shop sells packs of blue pens, packs of gold pens and packs of red pens.
There are
6 pens in each pack of blue pens
3 pens in each pack of gold pens
5 pens in each pack of red pens
On Monday,
number of packs of blue pens sold
: number of packs
of gold pens sold :
number of packs of red pens sold
= 6 : 2 : 3
A total of 114 pens were sold.
Work out the number of gold pens sold.
Step 1: Ratio of pens = 14 : 15 : 24 (multiply the number of pens in a pack by the ratio).
Step 2: Find the total of this ratio, so 14 + 15 + 24 = 53
Step 3: 212 ÷ 53 = 4
Step 4: Multiply the number of green pens in the ratio by the answer from step 3.
So 24 × 4 = 96
So 96 green pens were sold.

35) A shop sells packs of chocolate biscuits, packs of ginger biscuits and packs of plain
biscuits.
There are
8 biscuits in each pack of chocolate biscuits
10 biscuits in each pack of ginger biscuits
12 biscuits in each pack of plain biscuits
On Monday,
number of packs of blue pens sold
: number of packs
of gold pens sold :
number of packs of red pens sold
= 11 : 3 : 8
A total of 642 biscuits were sold.
Work out the number of chocolate biscuits sold.
36) A shop sells packs of black pens, packs of red pens and packs of yellow pens.
There are
8 pens in each pack of black pens
5 pens in each pack of red pens
3 pens in each pack of yellow pens
On Monday,
number of packs of black pens
sold :
number of packs of red pens
sold :
number of packs of yellow pens
sold
= 9 : 5 : 2
A total of 515 pens were sold.
Work out the number of black pens sold.

61 Angle Facts
What you need to know…
There are 360° in one full turn (or one full circle) and 180° in half a turn (or semicircle).
A right angle is 90° and is a quarter turn, and can be shown by a small square.
An acute angle is an angle less than 90°.
An obtuse angle is an angle between 90° and 180°.
A reflex angle is an angle between 180° and 360°.
The angles that meet at a point add to 360°, and the angles on a straight line add to 180°.
The angles in a triangle add to 180°

1. State whether each angle is acute, reflex or obtuse.
What you need to know continued…
The angles in a triangle add to 180°.
An equilateral triangle has 3 sides of equal length (the dashes on the lines show they are
equal in length). All of the angles are also equal and are 60°.
An isosceles triangle has 2 sides of equal length. The angles at the base of the equal sides
are equal.

Give square B a side length of 10 cm. This will give square B an area of 100 cm2.
Since the length of the side of square A is 60% of the length of the side of square B, the
length of square A would be 6 cm.
