Answer 4

First. do no longer hear to the guy above me. while you're working with a fragment you do divide as she stated. yet you may do the step listed under. while you're working with an entire style you progression the decimal 2 places to the main dazzling. EX: 5/10 =.5 (flow the decimal 2 to the main dazzling)=50% EX2: sixteen=1600% to alter a % back to a decimal/style you in undemanding terms flow the Decimal 2 places to the main dazzling. wish I helped.

Answer 5

let x be 4.777...

x=4.777...
10x=47.777....
10x-x=47.7777....-4.77777
9x=43
x=43/9

then turn 43/9 into percent

43/9x100%=4300/9%

so the answer is
4300/9 % (in fraction)
or
477 7/9% (in fraction)
or
477.78% (in decimal -> 2 places)

hope this helps
