Question

4. A ribbon is 3 metres long. I need 8 pieces of ribbon each 40 cm long. How centimetres shorter is the ribbon than the length I need? .​

Answer 1

Answer:

20 cm Shorter

Step-by-step explanation:

According to the information provided in the question it is given as

Length of ribbon = 3 meter

Need 8 piece of 40 cm long

We need to find the ribbon short in centimeter than the length he need

Let first converting the quantity into cm as answer needed in cm

1 m = 100 cm

3 m= 300 cm

Hence the length of ribbon in cm = 300 cm

So 8 piece of 40 cm = 8 x 40 =320 cm  

Hence required length is 320 cm

And  we have only 300 cm

So the Difference = required - actual

Putting the values we get the answer

Shorter length = 320cm -300 cm

                          = 20 cm

Hence 20 cm shorter is the ribbon than the  length  he read
