Answer 1

Fraction of this large square that has been shaded red can be found by applying the formula for fraction in infinitum.

Given: 1/4 of square is shaded red following all the bottom right quarter to infinitum.

To find: Fraction of large square shaded red

Solution::

$s \infty = a \div( 1 - r)$

[where a= 1/4;

r= common ratio

=> 1/4]

$s∞=1÷4÷(1−(1÷4))$

by solving the above equation you get 1/3 .

Explanation:

So, the fraction part of large square shaded is equal to-

1/4÷[1-1/4]

= 1/4 ÷ 3/4

= 1/4x 4/3 [division inverts to multiplication]

= 1/3

So, the fraction part of the large square shaded red is 1/3rd part.
