Answer: There are 30 1-meter pieces of ribbon he can cut.
Step-by-step explanation:
Since we have given that
Number of pieces of ribbon = 3
Length of each ribbon = 1 decameter
So, we know that
[tex]1\ decameter=10\ meter[/tex]
So, Total length of 3 pieces of ribbon is given by
[tex]3\times 10\\\\=30[/tex]
So, Number of 1- meter pieces of ribbon he can cut is given by
[tex]\frac{30}{1}=30[/tex]
