Answer 2

It seems like you've provided a series of equations or expressions with a pattern. Let's analyze them:

a) 3,5 : 7 b) 10,4 : 8 c) 26,1 : 3

a) 28,8 : 9 b) 25,8 : 6 c) 63 : 5

a) 1,37 : 2 b) 8,4 : 15 c) 11,16 : 18

a) 0,4 : 8

a) 0,3 : 5 b) 0,8 : 5

Let's try to find the pattern in each set:

a) 3,5 : 7 3 + 5 = 8, which is one less than 7 So, the pattern seems to be adding the two numbers and subtracting 1. 3 + 5 - 1 = 7 (which is the second number)

b) 10,4 : 8 10 + 4 = 14, which is one less than 15 So, the pattern seems to be adding the two numbers and subtracting 1. 10 + 4 - 1 = 13 (which is the second number)

c) 26,1 : 3 26 + 1 = 27, which is one less than 28 So, the pattern seems to be adding the two numbers and subtracting 1. 26 + 1 - 1 = 26 (which is the second number)

a) 28,8 : 9 28 ÷ 8 = 3.5, which is one less than 4.5 So, the pattern seems to be dividing the first number by the second number and subtracting 1. 28 ÷ 8 - 1 = 3 (which is the second number)

b) 25,8 : 6 25 ÷ 8 = 3.125, which is one less than 4.125 So, the pattern seems to be dividing the first number by the second number and subtracting 1. 25 ÷ 8 - 1 = 3 (which is the second number)

c) 63 : 5 63 ÷ 5 = 12.6, which is one less than 13.6 So, the pattern seems to be dividing the first number by the second number and subtracting 1. 63 ÷ 5 - 1 = 12 (which is the second number)

a) 1,37 : 2 1.37 × 2 = 2.74, which is one less than 3.74 So, the pattern seems to be multiplying the first number by the second number and subtracting 1. 1.37 × 2 - 1 = 2.74 (which is the second number)

b) 8,4 : 15 8.4 × 15 = 126, which is one less than 127 So, the pattern seems to be multiplying the first number by the second number and subtracting 1. 8.4 × 15 - 1 = 126 (which is the second number)

c) 11,16 : 18 11.16 × 18 = 200.88, which is one less than 201.88 So, the pattern seems to be multiplying the first number by the second number and subtracting 1. 11.16 × 18 - 1 = 200.88 (which is the second number)

a) 0,4 : 8 0.4 × 8 = 3.2, which is one less than 4.2 So, the pattern seems to be multiplying the first number by the second number and subtracting 1. 0.4 × 8 - 1 = 3.2 (which is the second number)

a) 0,3 : 5 0.3 × 5 = 1.5, which is one less than 2.5 So, the pattern seems to be multiplying the first number by the second number and subtracting 1. 0.3 × 5 - 1 = 1.5 (which is the second number)

b) 0,8 : 5 0.8 × 5 = 4, which is one less than 5 So, the pattern seems to be multiplying the first number by the second number and subtracting 1. 0.8 × 5 - 1 = 4 (which is the second number)

Please verify if these patterns match your expectations!
