1/15 – 1 клетка 3/5 – 9 клеток 7/15 – 7 клеток 9/15 – 9 клеток 4/5 – 12 клеток

Answer 3

┌───┬───┬───┬───┬───┐ │ 1 │ 2 │ 3 │ 4 │ 5 │ ├───┼───┼───┼───┼───┤ │ 6 │ 7 │ 8 │ 9 │10 │ ├───┼───┼───┼───┼───┤ │11 │12 │13 │14 │15 │ └───┴───┴───┴───┴───┘

The fraction 1/15 falls on the first cell of the 15-cell segment.

To mark 3/5, we need to divide the segment into 5 equal parts, then count 3 of those parts to find the location of 3/5. Each part consists of 15/5 = 3 cells, so three parts cover 3 x 3 = 9 cells, starting from cell 1. This means 3/5 falls on the 9th cell of the segment.

To mark 7/15, we divide the segment into 15 equal parts, each consisting of 1 cell. Then we count 7 parts starting from the first cell, which brings us to the 7th cell of the segment.

To mark 9/15, we can simplify the fraction to 3/5 and follow the same steps as before. Since 9/15 = 3/5, we count three parts of the segment starting from cell 1, which brings us to the 9th cell.

To mark 4/5, we need to divide the segment into 5 equal parts, each consisting of 3 cells. Then we count 4 parts starting from the first cell, which brings us to the 12th cell of the segment.

Therefore, the locations of the fractions are:

• 1/15: cell 1
• 3/5: cell 9
• 7/15: cell 7
• 9/15: cell 9
• 4/5: cell 12
