Barry made the model to show multiplying a fraction by a fraction. Which multiplication sentence does the model show? A grid with 3 rows of 6 columns showing 18 squares total. The 12 squares in the top two rows are shaded yellow, the 15 squares in the first 5 columns are shaded blue. The shading overaps to make green in 10 squares. 13×23=29 26×56=518 13×26=19 23×56=59

The correct option is D.

2 rows out of 3 are shaded yellow.

Fraction should be

Now

5 columns out of 6 are shaded blue.

Fraction should be

And,

10 out of 18 squares are green.

Fraction should be

Given:

Number of rows = 3

Number of columns = 6

Number of square boxes = 18

yellow square boxes in the top two rows = 12

Blue square boxes in the first 5 columns = 15

Number of green boxes (shading overlaps) = 10

To find:

The model to show multiplying a fraction by a fraction.

Solution:

2 rows out of 3 are shaded yellow.

Fraction for yellow =

5 columns out of 6 are shaded blue.

Faction for blue =

10 out of 18 squares are green.

Faction for green =  

Now,

Therefore, the correct option is D.

slope intercept form is y = mx + b
