In a store, 7/200 of the shirts are yellow and 69/600 are pink . What percent of the shirts are not yellow or pink.?

510/600 of the shirts are not yellow or pink.

Step-by-step explanation:

First we turn 7/200 with a denominator of 600.

7/200 = 21/600

Next we add 69/600 with 21/600.

69/600 + 21/600 = 90/600

Now we subtract 600 by 90.

600 - 90 = 510.

So, the answer is 510/600
