Write fraction or mixed number as a decimal
1. 2/5
2. 8/9
3. 3 3/4
4. 7/10
5. 2 3/8
6. 5/6

1. 0.4

2. 0.8888888889

3. 3.75

4. 0.7

5. 2.375

6. 0.3 the three is ongoing

Step-by-step explanation:

All you have to do is divide the numerator(top) by the denominator(bottom) and if there is a whole number than put that before the decimal

3. parallelogram

step-by-step explanation:

we turn each of our sides into direction vectors

ab=b-a=(3 - 7, 1 - 0) = (-4, 1)

bc=c-b=(1,6)

cd=d-c=(4,-1)

da=a-d=(-1,-6)

we see how the opposite sides have negated direction vectors; this is characteristic of a parallelogram.   we have congruent sides ab=cd and bc=da with unequal lengths because 1^2+6^2 is different from (-4)^2+1^2.   so it's not a square or a rhombus.  

we check the dot product of direction vectors of adjacent sides.   we have

ab dot bc = -4(1) + 1(6) = 2

that's not zero so the sides are not perpendicular.   we've ruled out rectangle.

the direction vectors indicate two pairs of congruent parallel sides, so we choose parallelogram over trapezoid.

answer: i guess 5 units?
