Answer 1

1. If Kayla has a red ribbon with length 25  9 m and piece of 5 7 m is cut from it and gave to Sania . Find how much long ribbon left with her?                                                                                                                                                                                                                      

• Kayla has a ribbon of length = 25 9 m.
• Part of ribbon give to Sania = 5 7 m.
• So, the length of the ribbon left =25 9 m - 5 7 m = 175  63 = 130  63 m
• So , the ribbon left with Kayla is 2.06 m .
