Question

the diagram shows 3/4 of a fraction strip shaded. Mary erases some of the shading to show 5/8. Explain in the steps the took to shade 5/8 of thr fraction strip.a. She divided the fraction strip into 3/4partsb. She converted 3/4 into a fraction with a numerator of .3/4= -/8c. -/8-5/8 = -/8 She erased. eight of the shaded areadraw a revised model to show the diagram after Mary erases the fraction of the area shown in the last step

Answer 1

We know that the diagram shows 3/4 of a fraction strip shaded.

Now, if Mary erases some of the shadings to show 5/8, that means she also added 4 more rectangles to have 8, then she shaded 5 of them.

Part A. She divided it by 3/4.

`((3)/(4))/((3)/(4))=1`

So, at this point, she got the whole unit without divisions.

Part B.
