57 · Fifty-seven packs 5 tens and 7 ones, written 57.
57 · Fifty means 5 tens and seven means 7 ones, so fifty-seven is 57.
forty · Forty is the decade word for 40. Fourteen sounds similar but means 14.
True · Ninety is the decade word for 90, just like the other decade words end in -ty.
83 · Eighty-three packs 8 tens and 3 ones, written 83.
fifty · After forty-nine, the count moves into the next group of ten: fifty.
eighty-three · The 8 in 83 means eight tens, read as eighty, with three ones, so eighty-three.
False · Alex is wrong. Eighty-five needs 8 tens first, written 85, not 58.
ninety-one · 91 is ninety plus one. The decade word ninety comes first, then a hyphen, then one.
100 · One hundred packs 1 hundred, 0 tens and 0 ones, written 100.
