Answer 1

Let the cost of 6 pairs of jeans cost x pounds.
Therefore,
x/6=60/4
or,4x=6*60
or x=(6*60/4)=90 pounds

Let the cost of 7 newspapers be x pence
therefore,
x/7=60/2
x=(60/2)*7=210 pence

Let the cost of 5 vases be x pounds
Therefore,
x/5=60/3
or,x=(60/3)*5=100 pounds

Answer 2

If 4 Pairs Of Jeans Cost £60, How Much Do 6 Pairs Of Jeans Cost?
= (£60 / 4) * 6
= £15 * 6
= £90

If 2 Newspapers Cost 60 pence, How Much Do 7 Newspapers Cost?
= (60 pence / 2) * 7
= 30 pence * 7
= 210 pence

If 3 Vases Cost £60, How Much Do 5 Vases Cost ?
= (£60 / 3) * 5
= £20 * 5
= £100

Answer 3

Let x be the cost of 6 pairs of jeans:
4 jeans : 60 = 6 jeans : x
x = 60 * 6 / 4
= 360 / 4
= 90 pounds

Let x be the cost of 7 newspapers
2 newspaper : 60 = 7 newspaper : x
x = 60 * 7 / 2
= 420 / 2
= 210 pence

Let x be the cost of 5 vases
3 vases : 60 = 5 vases : x
x = 60 * 5 / 3
= 300 / 3
= 100 pounds

Answer 4

Pairs Of Jeans:
1 Pairs Of Jeans cost : 60£/4=15
6 Pairs Of Jeans cost :15x6=90
Newspapers:
1 Newspapers cost 60/2=30
7 Newspapers cost : 30x7=210
Vases
1 vase cost : 60/3=20
5 vases cost :20x5=100

Answer 5

4<---->£60
6<--> (6/4) x £60 = 6 x £15 = £90

2<--> 60 p
7<->(7 / 2) x 60 p = 7 x 30 p = 210 p = £2.10

3<--> £60
5<-->(5/3) x £60 = 5 x £20 = £100

Answer 6

first find out cost of one item or pair by dividing cost by number of items/pairs, then calculate the cost of the required by multiplying cost of ech item/pair with number of requred items/pairs
a)
cost of one pair = 60/4 = 15
cost of 6 pairs = 15 * (6) = 90

b)
cost of one news paper = 60/2 = 30
cost of 7 news papers = 30 *(7) = 210 pence

c)
cost of each Vase = 60/3 =20
costf 5 vases = 20 *(5) = 100

Answer 7

(4/60) = (6/x) x = (60*6)/4 = 90

(2/60) = (7/x) x = (7*60)/2 = 210

(3/60) = (5/x) x = (5*60)/3 = 100

pay attention in school -.-

Answer 8

let me do one as an example
If 5 Pairs Of Jeans Cost £95, How Much Do 8 Pairs Of Jeans Cost?

----------------------------

5/95 = 8/x
5x = 95 * 8
5x = 760
x = 152
So 5 pairs cost £95, 8 pairs cost £152.

---------------------------

There's another way to do this, you find the cost of 1 pair
95/5 = 19

each pair cost £19, so 8 * 19 =£152


Hope this helps you answer the rest
