Question

Fraction of growth (increase in length) of a plant (in mm) over 7 days is given.


Which of the following gives the difference between minimum and maximum growth of the plant?

• A. $\frac{1}{7}$
• B. $\frac{2}{7}$
• C. $\frac{3}{7}$
• D. $\frac{4}{7}$

Answer 1

The correct option is C $\frac{3}{7}$

Let us plot the given points on the line plot.


Maximum amount of growth = $\frac{4}{7}$ cm

Minimum amount of growth = $\frac{1}{7}$ cm

Difference = $\frac{4}{7}$ -$\frac{1}{7}$ cm

= $\frac{3}{7}$ cm

Hence, the difference between the maximum and the minimum growth = $\frac{3}{7}$ cm
