The reciprocal of of 1 over 5

Answers

The reciprocal of 1/5 is: 5/1 or just 5.

To get the reciprocal of a fraction, it basically just means to flip the numbers. If you're dealing with a whole number (such as 5 in this case), you would divide 1 by the number, making it 1/5.

The perimeter of a rectangular field is 344 yards.  If the width of the field is 74 yards, what is its length

Answers

The perimeter of a rectangle is the length of two widths plus two lengths.  You have the width as 74 yard so your formula is 2(74) + 2L = 344.  2x74=148 so 148 + 2L=344.  Subtract 148 from both sides and get 196. 2L=196. Divide both sides by 2 and you get L= 98

P = 2L + 2w

344 = 2L + 2·74

344 - 148 = 2L

2L = 196

L = 196 : 2

L = 98 yards
