Answer:
Rows are the steps - they go left to right and are numbered 1,2,3,... Columns are the columns - they go up and down and are lettered A,B,C,... Cells are defined by the row and column they are in.
Step-by-step explanation:
1/5 full =250g
4/5 full =550g
550g-250g=300g=3/5 without jug
1/5 without jug=300g/3=100g
250g-100g=150g
<u>The jug weighs 150g empty</u>
I’m assuming you mean there are 5 rows which are equal, and use all the 115 photos. If this is the case then 115/5 is 23 photos per row.
