Sarah paints a straight line. the line is 13 1/2 ft long. she wants to divide the line into sections that are each 18 ft long.

how many sections will the line be divided into?

The number of sections made is

Solution:

Given that, Sarah paints a straight line

The line is feet

She wants to divide the line into sections that are each 18 ft long

To find: Number of sections

From given,

Number of sections can be found by dividing the total length of line by length of 1 section

Substituting the values, we get,

Thus number of sections made is

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

answer is 12345678900987654321234567890987654321
