Answer:
The underlined number is the answer!
Solution:
#1
Since
X : 7 = 24 : 56
Then we know
X/7 = 24/56
Multiplying both sides by 7 cancels on the left
7 × (X/7) = (24/56) × 7
X = (24/56) × 7
Then solving for X
X = 7 × (24/56)
X = 3
Therefore
3 : 7 = 24 : 56
_____
#2
Since
8 : 3 = X : 15
Then we know
8/3 = X/15
Multiplying both sides by 15 cancels on the right
15 × (8/3) = (X/15) × 15
15 × (8/3) = X
Then solving for X
X = 15 × (8/3)
X = 40
Therefore
8 : 3 = 40 : 15
_____
#3
Since
12 : X = 15 : 5
Then we know
X/12 = 5/15
Multiplying both sides by 12 cancels on the left
12 × (X/12) = (5/15) × 12
X = (5/15) × 12
Then solving for X
X = 12 × (5/15)
X = 4
Therefore
12 : 4 = 15 : 5
_____
#4
Since
4 : 16 = X : 8
Then we know
4/16 = X/8
Multiplying both sides by 8 cancels on the right
8 × (4/16) = (X/8) × 8
8 × (4/16) = X
Then solving for X
X = 8 × (4/16)
X = 2
Therefore
4 : 16 = 2 : 8
_____
#5
Since
27 : X = 9 : 15
Then we know
X/27 = 15/9
Multiplying both sides by 27 cancels on the left
27 × (X/27) = (15/9) × 27
X = (15/9) × 27
Then solving for X
X = 27 × (15/9)
X = 45
Therefore
27 : 45 = 9 : 15
_____
#6
Since
11 : X = 330 : 450
Then we know
X/11 = 450/330
Multiplying both sides by 11 cancels on the left
11 × (X/11) = (450/330) × 11
X = (450/330) × 11
Then solving for X
X = 11 × (450/330)
X = 15
Therefore
11 : 15 = 330 : 450
_____
#7
Since
35 : X = 20 : 8
Then we know
X/35 = 8/20
Multiplying both sides by 35 cancels on the left
35 × (X/35) = (8/20) × 35
X = (8/20) × 35
Then solving for X
X = 35 × (8/20)
X = 14
Therefore
35 : 14 = 20 : 8
_____
#8
Since
12 : 15 = X : 10
Then we know
12/15 = X/10
Multiplying both sides by 10 cancels on the right
10 × (12/15) = (X/10) × 10
10 × (12/15) = X
Then solving for X
X = 10 × (12/15)
X = 8
Therefore
12 : 15 = 8 : 10
_____
#9
Since
5 : X = 30 : 18
Then we know
X/5 = 18/30
Multiplying both sides by 5 cancels on the left
5 × (X/5) = (18/30) × 5
X = (18/30) × 5
Then solving for X
X = 5 × (18/30)
X = 3
Therefore
5 : 3 = 30 : 18
_____
#10
Since
20 : 12 = 15 : X
Then we know
12/20 = X/15
Multiplying both sides by 15 cancels on the right
15 × (12/20) = (X/15) × 15
15 × (12/20) = X
Then solving for X
X = 15 × (12/20)
X = 9
Therefore
20 : 12 = 15 : 9
