Answer:b 5,400 ÷ 60Step-by-step explanation:knoweth thay multiplication table.what are the multiples of 9 ?1×9 = 92×9 = 183×9 = 274×9 = 365×9 = 456×9 = 547×9 = 638×9 = 729×9 = 8110×9 = 90because multiples of 10 follow the same structure, we just add 0s.so, the multiples of 90 are the same numbers as above, they just have a 0 at the end. and if we also multiply the first numbers (1 ..10) by 10, the results get a second additional 0 at the end. so, when we look at3600540064007200we actually look at3654647236 = 4×9so, 3600 has to be divided by 40 to result in 90.but it is divided by 50. so, no.54 = 6×9so, 5400 has to be divided by 60 to result in 90.and it is. so, yes ! 5400 ÷ 60 = 9064 is no factor of 9 at all. so, no.72 is 8×9so, 7200 has to be divided by 80 to result in 90.but it is divided by 90. so, no.
