Pat has some T-shirts. 1/4 of the T - shirts are pink, 1/2 of the remainder are white and the rest are purple. what fraction of the T-shirts are purple

1/4 if the T-shirts are purple.

to answer this, you need to find the greatest common denominator

1/2=2/4

1/4=1/4

2/4 plus 1/4 is 3/4 t-shirts.

2/4+1/4=3/4

so, u subtract the total amount of t-shirts (4/4 t-shirts) with the amount of pink (1/4 t-shirts) and white (2/4 t-shirts), which u get 1/4 purple t-shirts.

4/4-3/4=1/4

so, pat has 1/4 purple t-shirts.
