Answer 1

Ответ:

Пошаговое объяснение:

24:6 = 32:8

84:12 = 35:5

x/9 = 2/3

x = 9*2 / 3

x = 18/3

x = 6

Answer 3

To solve these proportions, we can use the concept that the ratios on both sides of the equation should be equal. Here's how you can solve each proportion:

1. 24:6 = 32:2 Let's simplify both sides: 24 ÷ 6 = 4 32 ÷ 2 = 16 Now, check if the two simplified ratios are equal: 4 = 16 Since 4 is not equal to 16, this proportion is not valid.

2. 84:12 = :53 Let's find the value of the missing ratio on the left side: 84 ÷ 12 = 7 Now, we have: 7:53 This proportion is valid.

3. :9 = 2:3 Let's find the value of the missing ratio on the left side: If we cross-multiply, we get: (unknown value) × 3 = 9 × 2 To solve for the unknown value, divide both sides by 3: (unknown value) = (9 × 2) / 3 (unknown value) = 18 / 3 (unknown value) = 6 Now, we have: 6:9 = 2:3 This proportion is valid.

So, the valid proportions are:

2. 84:12 = 7:53
3. 6:9 = 2:3
