The left column of the chart lists the lengths of input pieces of ribbon. Stretching machines are listed across the top. The other entries are the outputs for sending the input ribbon from that row through the machine from that column. Copy and complete the chart.

Solution:

Given, the left column of the chart lists the lengths of input pieces of ribbon.

Stretching machines are listed across the top.

The other entries are the outputs for sending the input ribbon from that row through the machine from that column.

We have to complete the chart.

We know, Input × stretching power = Output

First column, input × 2 = 1

Input = 1/2

For second column,

1/2 × stretching power = 5

Stretching power = 10

From third row, 3 × 2 = 6

Similarly, 3 × 5 = 15

From fourth row, input × 2 = 14

Input = 14/2 = 7
