What is 11/12 minus 2/3

Step-by-step explanation:

2/3 = 8/12

11/12-8/12 = 3/12 = 1/4

1/4

Step-by-step explanation:

11/12 - 2/3

We need to get a common denominator of 12

11/12 - 2/3 *4/4

11/12 - 8/12

3/12

We can simplify by dividing by 3 on top and bottom

1/4

step-by-step explanation:

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)
