→ Easy, all you have to do it divide the total length (30cm) by the desired length (3 3/4)
So the equation is:
30/3 3/4
Which looks really weird when written like that. So the first thing we should do is change how we write 3 3/4.
3 3/4 is short hand for 3 and 3 quarters.
3 + (3/4)
= 3 + 0.75
= 3.75 cm
