I'm gonna show fractions the other way
2/3 + 1/9
first u have to make them have common denominators
2/3 multiply both numbers by 3 to make it equal to 1/9 u get6/9 the u can add the numerators 6/9 with 1/9 it 7/9
then for numbAH 2 u have to multiply both numbers in 2/3 by 7 and both numbers in 2/7 by 3 u get 14/21-6/21 then u just subtract the numerators
numerater= top number
dennomonater=bottom number

2/3 + 1/9 = 6/9 + 1/9 = 7/9
2/3 - 2/7 = 14/21 - 6/21 = 8/21

2/3 + 1/9
6/9 + 1/9 = 7/9
2/3 - 2/7
14/21 - 6/21 = 8/21

Your stupid nephew isn't getting any smarter in math with all the questions you have helped him with in the past. Maybe your stupid nephew should get out his math book and figure it out on his own and stay off the Internet while HE is doing homework,

Nice. You just keep on supporting him and being a nurturing caring adult in his life. He'll thank you for it later.
Why would anyone call a child stupid? Will it help them learn? I noticed you didn't care to share your answers BEFORE you asked others to show you how to answer.

Keep on saying it. A grown- up is wiser than a child.
