Well, to cover the whole bridge, is 6/6, or 1 whole

so hmmm $\bf \begin{array}{ccllll}
concrete&bridge\\
\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\
\frac{4}{5}&\frac{5}{6}\\\\
x&\frac{6}{6}
\end{array}\implies \cfrac{\frac{4}{5}}{x}=\cfrac{\frac{5}{6}}{\frac{6}{6}}\implies \cfrac{\frac{4}{5}}{\frac{x}{1}}=\cfrac{\frac{5}{6}}{\frac{6}{6}}$

$\bf \cfrac{4}{5}\cdot \cfrac{1}{x}=\cfrac{5}{6}\cdot \cfrac{6}{6}\implies \cfrac{4}{5x}=\cfrac{5}{6}\implies 4\cdot 6=5\cdot 5x\implies 24=25x
\\\\\\
\boxed{\cfrac{24}{25}}=x$

Convert 7500cm to meters

olya-2409 [2.1K]

Answer: 75 meters

Step-by-step explanation: In this problem, we're asked to convert 7,500 centimeters into meters which means we use the conversion factor for centimeters and meters.

Conversion factor ⇒ <em>100 centimeters = 1 meter</em>

Next, notice that we're converting from a smaller unit "centimeters" to a larger unit "meters" and when we convert from a smaller unit to a larger unit we divide by the conversion factor.

So we divide 7,500 by the conversion factor which is 100.

7,500 ÷ 100 = 75

Therefore, 7,500 centimeters = 75 meters.
