The figure, not drawn to scale, consists of 1 Rectangle D and 1 Square E whose areas are in the ratio of 3 : 1. Given that
313 of Rectangle D is shaded, what fraction of Square E is shaded?
Area of Rectangle D |
Area of Square E |
3x13 = 39 u |
1x13 = 13 u |

Area of Rectangle D is the repeated identity.
Shaded area of Rectangle D is the same as the shaded area of Square E.
LCM of 3 and 13 = 39
Fraction of Square E that is shaded
=
913 Answer(s):
913
