1. 3/7, __ 14
2. 7 to 5, __ to 15
3. 15:5, 3:__
you try to find a wy that can make the statement true so for example 3/7 is __ 14, 7 can become 14 be multiplying by 2 and what you do to one side you do to the other
3/7, 6/14
7 to 5, 21 to 15
15:5, 3:1
Right!
To solve these questions, we need to find the missing numbers that will form a proportional relationship with the given numbers.
1. To find the missing number between 3/7 and 14, we can set up a proportion:
(3/7) = (x/14)
Cross-multiplying, we get:
3 * 14 = 7 * x
Solving for x, we have:
42 = 7x
Dividing both sides by 7, we find:
x = 6
Thus, the missing number is 6.
2. To find the missing number between 7 to 5 and 15, we can set up a proportion:
(7/5) = (x/15)
Cross-multiplying, we get:
7 * 15 = 5 * x
Solving for x, we have:
105 = 5x
Dividing both sides by 5, we find:
x = 21
Thus, the missing number is 21.
3. To find the missing number between 15:5 and 3:?, we can set up a proportion:
15/5 = 3/x
Cross-multiplying, we get:
15 * x = 3 * 5
Solving for x, we have:
15x = 15
Dividing both sides by 15, we find:
x = 1
Thus, the missing number is 1.
By setting up proportions and solving for the missing numbers, we can find the answers to these questions.
