Broderick had $420 in his checking account he may six deposit of $35.50 each he needs to write more checks for $310.75 each

He can only make two $310.75 checks because $35.50x6=$213
$213+$420=$633
$633-$310.75=$322.25

That means u can make another check
$322.25-$310.75=11.5
So you can make two checks of $310.75

128/3reason being 5 and 1/3 = 16/316/3 • 2/3 = 32/31 and 1/3 = 4/3 32/3 • 4/3 this will equal 128/3
