If i eat 2 out of 8 pieces, how much percent is left

75%

Step-by-step explanation:

8/8 - 2/8 = 6/8

6/8 = 3/4

3 ÷ 4 = 0.75

0.75 ⋅ 100 = 75%

75%

Step-by-step explanation:

1. divide.

2/8 = 0.25

0.25 is 25% of 1,

that leaves 75% left,

so the answer is 75%

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
