Question

A plant that id 15 7/8 cm high grows x cm to a height of 19 3/8cm . Write and solve the equation to find the amount of growth.​

Answer 1

Original height of the plant =

$15 \frac{7}{8} cm$

New height of the plant =

$19 \frac{3}{8} cm$

Height by which the plant grows = X cm

.°. original height + x = new height

$15 \frac{7}{8} + x = 19 \frac{3}{8}$

$= > x = 19 \frac{3}{8} - 15 \frac{7}{8}$

$= > \frac{155}{8} - \frac{127}{8} = \frac{155 - 127}{8}$

$= > \frac{28}{8} = \frac{7}{2} = 3 \frac{1}{2}$

So, the amount of growth =

$3 \frac{1}{2} cm$

Hope it helps♥.
