Question

How many pieces, each of length 15 1/10
cm, can be cut from a ribbon of length 181 1/5 m?​

Answer 1

Answer: 12,000

Step-by-step explanation:

Length of ribbon = 181 1/5 m

                            =906/5 m

                            = 906/5 * 1000 cm

                            =181200 cm

length of smaller pieces required = 15 1/10 cm

                                                       =151/10 cm

NO. OF PIECES THAT CAN BE CUT FROM THE LARGER RIBBON =  LENGTH OF LARGER RIBBON/ LENGTH OF SMALLER RIBBON

= 181200/151/10

= 181200*10 /151

=1200*10

=12,000 smaller pieces.

                                                       

Answer 2

Answer:

Length of a ribbon = 181 1/5m

= 906/5m

= 906/5 × 1000cm

= 906 × 200cm

= 181200cm

Length of pieces can be cut from ribbon of length 181200cm = 15 1/10cm

= 151/10cm

Number of pieces can be cut from the ribbon of length 181200cm =

181200cm ÷ 151/10cm

= 181200cm × 10/151cm

= 1200cm × 10cm

= 12000

Hence, 12000 pieces of each length of 15 1/10cm can be cut from a ribbon of length 181 1/5m.
