Idon't know how to do ! in a study of bat migration habits, 240 male bats and 160 female bats have been tagged. if 100 more female bats are tagged, how many more male bats must be tagged so that 3/5 of the total number of bats in the study are male?

150 more male bats need to be tagged

if you want 2/5 to be female you divide the 260 (<160+100) by 2 to get 130
then you multiply 130 by 3 to get the total amount of male bats that need to be tagged
130*3=390
then you subtract 240 from the 390 to find out how many more bats need to be tagged
390-240=150

Idrk but i think u should figure out the n dia n then the units it will make it way more easier
