Vasu tyagi from St Joseph's High school, Panvel

Length of a ribbon she cut is 18m(6×3).so the answer is B (x-18)cm.

Ans 4:

Shreyasi Padihary from The Cambridge International School , Bangalore
Class : Class 7
The correct answer is C..If you pay close attention to the question, you will realize that it says Xm not X cm. She cuts of 6 pieces of ribbon measuring 3cm each. 6 multiplied by 3 is equal to 18cm. Now to subtract 18 cm from Xm we must convert Xm into cm. We can do this by multiplying X into 100 , which is equal to 100X. Next we will subtract 18cm from 100X which is equal to (100X-18)cm. Thus the correct answer is C. Hope you found it helpful :)
