3 1,2:2 1,7=2 1,3 :t

It looks like you’re presenting a proportion equation: \[ \frac{3}{1.2} : \frac{2}{1.7} = \frac{2}{1.3} : t \] To solve for \( t \), we can set up the equation based on the property of proportions: \[ \frac{3}{1.2} \cdot t = \frac{2}{1.7} \cdot \frac{2}{1.3} \] Now let's calculate: 1. Calculate \( \frac{2}{1.7} \cdot \frac{2}{1.3} \). \[ \frac{2}{1.7} \cdot \frac{2}{1.3} = \frac{4}{1.7 \cdot 1.3} \] Calculating \( 1.7 \cdot 1.3 \): \[ 1.7 \cdot 1.3 = 2.21 \] So, \[ \frac{2}{1.7} \cdot \frac{2}{1.3} = \frac{4}{2.21} \] 2. Now we need to calculate \( \frac{3}{1.2} \cdot t \): \[ \frac{3}{1.2} = 2.5 \] So we have: \[ 2.5t = \frac{4}{2.21} \] 3. To find \( t \), divide both sides by \( 2.5 \): \[ t = \frac{4}{2.21 \cdot 2.5} = \frac{4}{5.525} \] Now calculate: \[ t \approx 0.723 \] Thus, the value of \( t \) is approximately \( 0.723 \).
