6.9
Make 62.1 to 621 to remove the decimal
Then work through and you 69. Then add the decimal back in to get 6.9
630

 Calculate by doing 3/4 x 840
 “of” in maths means multiply
 ^{3}/_{4} * ^{840}/_{1}
 ^{Simplified……..3}/_{1} * ^{210}/_{1}
 630
2.03; 2.300; 2.302; 2.32
 If not sure, put numbers in column format
1.75kg
 Convert to grams firstly to make it easier to calculate
 2500750 = 1750
 Then convert back remembering 1000g = 1kg
 1.75kg
a) 1/15
 Convert to the same denominator
 So this would mean Tom 3/5 = 9/15 and Jerry 1/3 = 5/15
 In total, 14/15ths has been eaten leaving 1/15
b) 250g
 If Tom had 3/5 = 150g, then 1/5 = 50g
 Therefore 5/5 = 250g
D C A B
A. 1/7
B. Very small / minimal chance
C. 1/6
D. 1/2
a) 8.52am
8.15am + 37mins = 8.52am
b) 5.46pm
6.23pm – 37mins.
Slightly harder to calculate so take off 23mins first to get to 6pm. This leaves 14mins (3723). So then take 14mins off 6pm
So 5.46pm
a) £102
10metres would be £10.20 * 10 = £102
b) 2.5metres
£10.20 * 2 = £20.40. This leaves £5.10 (£25.50 – £20.40)
£5.10 is exactly half of £10.20. So therefore total is 2.5 metres
200miles
 Calais to Paris is 320km. So 320 * 5/8 = number of miles
 200miles. Can be done in 1 of 2 ways. Per the above or work out 1/8th which would be 40km. Then 5 * 40km = 200m
600g
 2:1 Flour:Fat
 900g of pastry required. Given we have 3 parts, therefore each part is 300g
 Flour is 2 parts so 2 * 300 = 600g
12:00pm
 The way to look at this is the lowest common multiple of 3,5 & 8.
 This is best done by doing your 8 times table and finding the first number that 3 & 5 also go into
 This is 120. So equivalent is 120 minutes
 Time is 12:00
a) 27
 The cube is 3 deep and each face has 9 cubes. So total is 27
b) 8
 3 Blue faces will be on each corner
 In total, there are 8 corners
c) 24
 Each side has 4 faces. Its 6 sides * 4 = 24
d) 0
There are no faces with EXACTLY 2 other small cubes.
a) 160cm
b) 168cm²
49
 Look for multiples of 7 between 20 and 80
 So 21,28,35,42,49,56,63,70,77
 49 is the only one that will be a multiple of 5 next year
Area = 200cm²
 If 2x long as wide, then need to calculate each side
 Double length v width means length is 20cm and width is 10
 Area = 200cm²
a) 4mins
Sally less Anna
b) 80mins
15 + 17+ 14+ 18+ 16
c) 16mins
80/5
d) 1km
Peter took 15mins. If its 4km/h he walks, then after 15mins, he walks 1km
a) 27
8 * 9 = 72. Clotted = 27
b) 6
To give 42, reverse would be 24. So 4 * 6 = 24
c) 5 & 7
Reverse would be 35. So 2 whole numbers would be 5 & 7
