Question

A loaf has a mass of x grams. if it is cut into four equal pieces, what is the mass of each piece​

Answer 1

I will take an example with real numbers :

The loaf has a mass of 200 grams

To be cut into 4 equal pieces, each piece must have the mass of 50 grams.

And, the proportion of 50 to 200 is 1/4

So, we can conclude that the mass of each piece = x/4.
