At Danny's Doggie Daycare, there are 12 poodles and 10 chihuahuas. If 6 extra poodles joined today's group, how many extra chihuahuas would have to join, for the ratio to remain the same? Plz Help

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
