Question

875. 1) 3,5 : 7;10,4 : 8;26,1: 3;​

Answer 1

3,5 : 7 = 0,5

10,4 : 8 = 1,3

26,1 : 3 = 8,7

Answer 2

It seems like you're presenting a sequence of numbers and asking for the pattern or rule that governs the sequence. Let's try to analyze the given sequence:

3, 5 : 7 10, 4 : 8 26, 1 : 3

In each pair, there's a pattern that relates the first two numbers to the third number. Let's break down each pair:

1. 3, 5 : 7

   • If we take 3 + 5, we get 8, which is one less than the third number, 7.

2. 10, 4 : 8

   • If we take 10 - 4, we get 6, which is two less than the third number, 8.

3. 26, 1 : 3

   • If we take 26 / 1, we get 26, which is three times the third number, 3.

So, it appears that the relationship between the first two numbers and the third number involves basic arithmetic operations:

1. Addition: 3 + 5 = 8 (one less than 7).
2. Subtraction: 10 - 4 = 6 (two less than 8).
3. Division: 26 / 1 = 26 (three times 3).

The pattern here is that each pair of numbers relates to the third number through a specific arithmetic operation. Therefore, the pattern seems to be:

(Number1 [operation] Number2) = Third Number

You can apply this pattern to other pairs of numbers to predict the third number in each case.
