Order 5/8, 60%, and 0.62 from least to greatest.

60%, 0.62, 0.625

Step-by-step explanation:

Step 1: Convert 5/8 to decimal form.

In order to convert a fraction to a decimal, we divide the numerator (top) by the denominator (bottom). By dividing 5 by 8, we can get the fraction 5/8 in decimal form, which is 0.625

Step 2: Convert 60% to decimal form.

In order to convert a percentage to a decimal, all we have to do is move the percentage's decimal point two spots to the left. Since 60% shows us no decimal point, we can assume that it comes directly after the 0, or 60.0%. After moving the decimal point two spaces to the left, we find that 60% = 0.60 in decimal form.

Step 3: Compare the numbers.

Since 0.62 is already in decimal form, we don't need to make any changes. This means that we can compare the numbers we just found as well as 0.62. Since our numbers would be 0.625 (5/8), 0.60 (60%), and 0.62, from least to greatest we would get 60%, 0.62, 0.625

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.
