2 ⅔ - 1 ¾

please explain how you got the answer!

2 2/3 - 1 3/4 = 11/12

Step-by-step explanation:

You could convert them both to improper fractions then you would make them have common denominators so the least common denominator for the would be 12 so you would multiply them and then you would subtract them to get your answer of 11/12.

2 2/3 = 8/3 times 4 = 32/12

1 3/4 = 7/4 times 3 = 21/12

32/12 - 21/12 = 11/12

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

24/56=hx^7
