24. Yulduzcha o'miga qanday raqam qo'yish mumkin: 196 = 2 · 2 · * · 7

To find the missing number, we need to solve the equation:

\( 196 = 2 \times 2 \times \text{*} \times 7 \)

First, multiply the known numbers:

\( 2 \times 2 \times 7 = 4 \times 7 = 28 \)

Now, divide 196 by 28 to find the missing number:

\( 196 \div 28 \)

We can simplify this division. Since \( 28 \times 10 = 280 \), the number is less than 10. Let's try multiplying 28 by a number that ends in 6 when multiplied by 8 (since 8 × 7 = 56). Let's try 7.

\( 28 \times 7 = (20 + 8) \times 7 = 140 + 56 = 196 \)

So, the missing number is 7.
