First you get the answer you divide by 9 since it is the denominator and ultimately means how many "pieces" or parts the whole number or amount will be in. You divide by 9 and get 289. Now you have the 1/9 part of 2601. You now multiply this number by 4 to get the 4/9 of 2601. Whennyou multiply by four you get 1156. I hope this makes sense and that it helps you. Please mark brainliest if it did help. :)
