if the whole bar is 3 units long what is the length of the shaded bar write a miltiplication equation for the diagramand then solve please help class=

Respuesta :

This question can be solved with the help of a ruler. We first measure the length of the entire bar. This represents 3 units. Then, we measure the shaded region and this will represent x units. We then apply a ratio to get the equation:
measure length of entire bar * x = measured length of shaded region * 3

Length of the shaded bar ( x ) :
x = 3/4 · 3 =
= 9 / 4 = 2.25
Answer:
The length is 2.25 units.
