Answer 1

Hi! :)

There are 100 centimeters in 1 meter.

1 and 1/4 meters can also be written as 1.25, since 1/4 = 0.25.

To find the answer, convert 1.25 meters to centimeters.

1 meter = 100 centimeters
1.25 meters = x centimeters
1.25 is 125% of 1. In other words, there is a 25% increase.

Now apply this increase to the centimeters side.
125% = 1.25
1.25 x 100 = 125

So 1.25 meters (1 and 1/4 meters) equals 125 centimeters.

The string is 325 centimeters.
In order for the string to be 125 centimeters, you need to cut some off.
To find how much you need to cut off, subtract 125 from 325.
325 - 125 = 200

In order for your string to be 1 and 1/4 meters, you must cut 200 centimeters off the original 325 centimeter long string.

Answer: 200 centimeters
