in a load of laundry 70% of the socks in the load are white if there are 30 socks in the load how many are white

The answer is 21 white socks.

WORK: there are a few approaches you can take to solve this one, but the one i used is converting 70% into a decimal so. 7 Then i multiplied. 7 x 30 and got the answer of 21. Another way to solve this is by finding 10% of 30 which is simple, it's 3! You can get this by doing 30/10. After you conclude that 3 is 10% of 30, you do 3 x 7 and get 21. You multiply by 7 here since 10% x 7 is 70% and that's what the question wanted.

70/100=x/30

Cross multiply

(70) (30) = 100x

2100=100x

Divide by 100

x=21
