How many pieces of wire 3.6cm long can be cut from a coil of 1m long?What is the length of the piece left over?​
sp2606 [1]

Answer:

We can get 27 pieces of wire 3.6 cm long and have a piece 7/9 cm left over

Step-by-step explanation:

Find the "unit length" by dividing 1 m by 3.6 cm:

  1 m

-----------

3.6 cm

Recall that 1 m = 100 cm.  Multiply the following by the conversion factor 100 cm / 1 m:

  1 m            100 cm

----------- * ----------------- = 27,7777777...

3.6 cm            1 m

We can get 27 pieces of wire 3.6 cm long and have a piece 7/9 cm left over (verify this by dividing 7 by 9 on a calculator).
