4,9:0,35=х:35

To solve the equation \( \frac{4.9}{0.35} = \frac{x}{35} \), we can use cross-multiplication.

1. Cross-multiply: \[ 4.9 \times 35 = 0.35 \times x \]

2. Calculate \( 4.9 \times 35 \): \[ 4.9 \times 35 = 171.5 \]

3. Now we have: \[ 171.5 = 0.35x \]

4. To find \( x \), divide both sides by 0.35: \[ x = \frac{171.5}{0.35} \]

5. Calculate \( \frac{171.5}{0.35} \): \[ x = 490 \]

Thus, the value of \( x \) is \( 490 \).
