Acarpenter cut board that was 3/4 foot long from a board that was 5 1/4 feet long. how long was the remaining piece of wood?

4 1/2 feet

You find the amount remaining by subtracting the cut length from the original length:

... remaining = 5 1/4 - 3/4

... = 5 +1/4 -3/4 . . . . . . rearrange the problem a bit

... = 5 + (1/4 -3/4) = 5 + (-2/4) = 5 - 1/2 . . . . . . add the fractional parts

... remaining = 4 1/2 . . . . . . . . . . subtract the fraction from the whole number

Units are feet.

We assume you know that 1 - 1/2 = 1/2, so (4 + 1) - 1/2 = 4 + (1 - 1/2) = 4 1/2.

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
