Here come the answers.Highlight or tick the relevant statement on the learning journey.
Level 4This number is divisible by 3 because 144 ÷ 3 = 48
This number is not divisible by 7 because 7 x 20 = 140 and 7 x 21 = 147
Level 4
144 is a square number because 12 x 12 = 144
144
To the nearest 10 = 140
To the nearest 100 = 100
Level 5
240 is the lowest common multiple of 48 & 60
48, 96,144, 192 , 24060, 120, 160, 240
Level 5
12 is the highest common factor because it is the biggest number which is a factor of both
48 and 60.
48 & 60
Level 7
HCF –2 x 2 x 3 = 12 LCM –2 x 2 x 2 x 2 x 3 x 5
Level 62 x 2 x 2 x 2 x 3 = 48
24 x 3 = 48
2 x 2 x 3 x 5 = 6022 x 3 x 5
Level 4Factors of 48

Level 4 Question Answers & Working Out
A girl worked out the cost of 8 bags of apples at 47p a bag.
Her answer was £4.06.
Use estimation to say whether you think she is right or wrong.
Explain your answer.
47p rounded to the nearest 10 is 50p
50p x 8 = £4.00
Therefore the apples must have cost less than £4.00 not more.
Level 5 Question Answers & Working Out
a)Round 2.75037 to 1 decimal place
b)Write down a number that would be 3.4 when rounded to 1 decimal place.

11.83 to four significant figures
Level 7 Question Answer & Working Out
Multiplying makes numbers bigger. When is this statement true and when is it false?
False when:-Multiplying a positive number by a negative number e.g. 2 x – 3 = -6Multiplying by a number between 0 and 1e.g. 8 x 0.2 = 1.6Multiplying by 0e.g. 10 x 0 = 0True when:-Multiplying a negative number by a negative number and multiplying by a number greater than one.
Division makes things smaller. When is this statement true and when is it false?
False when:-Dividing a negative number by a negative number e.g. -6 ÷ - 3 = 2Dividing a negative number by a positive number.e.g. -8 ÷ 2 = -4Dividing by a number between 0 and 1e.g. 8 ÷ 0.2 = 40True when:-Dividing a positive number by a negative numbere.g. 8 ÷ - 4 = -2 Dividing a positive number by a number greater than one.42 ÷ 6 = 7
Level 8 Question Answer & Working Out
a) Write 734.6 in standard form
b) Write 6.3 x 10-3 as an ordinary number.
a) 7.346 x 102
b) 0.0063
c) Sir Isaac Newton was a mathematician, physicist and astronomer. In his work on the gravitational force between two bodies he found that he needed to multiply their masses together.Work out the value of the mass of the Earth multiplied by the mass of the Moon.Give your answer in standard form.Mass of Earth = 5.98 × 1024 kgMass of Moon = 7.35 × 1022 kg
5.98 x 7.35 = 43.953
1024 x 1022 = 1046
43.953 x 1046
= 4.3953 x 1047
