Calculating the Cost of Fabric

To calculate the cost of 2 1/4 meters of fabric, we can use the given information that 7/10 meters of fabric cost 12/5 thousand rubles.

First, let's find the cost of 1 meter of fabric: 1. Cost of 7/10 meters of fabric: 12/5 thousand rubles 2. Cost of 1 meter of fabric: (12/5) / (7/10) = (12/5) * (10/7) = 24/7 thousand rubles

Now, we can calculate the cost of 2 1/4 meters of fabric: 3. Cost of 2 1/4 meters of fabric: (2 + 1/4) * (24/7) = (9/4) * (24/7) = 216/28 = 54/7 thousand rubles

So, 2 1/4 meters of such fabric would cost 54/7 thousand rubles.
