Question

Se tiene 2 metros de tela y se corta el 85% para hacer cortinas el 50% del resto para hacer las tiras que la sujetan.¿cuantos sentimetros de tela quedaron?

Answer 1

For this case we have the following statement:

"You have 2 meters of fabric and you cut 85% to make curtains, 50% of the rest to make the strips that hold it. How many centimeters of fabric were left?"

So, we have:

2 meters ---------> 100%

x ----------------------> 85%

Where "x" represents the amount of fabric meters equivalent to 85%.

$x = \frac {85 * 2} {100}\\x = 1.7$

Thus, 1.7 meters of fabric were used to make curtains.

There are 0.3 meters of fabric left, of which half (50%) is used to make the strips that hold the curtain. That is to say:

$\frac {0.3} {2} = 0.15m$

Thus, 0.15 meters of fabric remain.

$0.15 m * \frac {100 cm} {1 m} = 15\ centimeters.$

Thus, 15 cm of fabric remain

Answer;

15 cm
