Of the shapes shown, 1/3 are circles and 1/12 are rectangles. What fraction of the shapes are either circles or rectangles?

5/12

Step-by-step explanation:

Fraction left f circles = 1/3

Fraction of rectangles = 1 /12

Fraction that are either circles or rectangles:

1/3 + 1/ 12

L.C. M of 3 and 12 = 12

(4 + 1) / 12

5/12

Fraction of shapes that are either circle or rectangle = 5/12

the answer is 99.
