Respuesta :
Kira's fish weighed more. I made them to be equivalent fractions. I know that 3 and 8 are both multiples of 24. So 2/3 x 8/8= 16/24. Then, 7/8 x 3/3= 21/24. Therefore, 7/8 is greater than 2/3
Kira's fish weights more because 2/3 would be a lot but would weight a little bit but 7/8 is a little bit but 7/8 weights more hope I helped
