Divide. Reduce the answer to the lowest terms.

3/8 ÷ 1/7

(21/8) (no parenthesis required)

or

2 and 5/8 (no "and" required)

Step-by-step explanation:

When you divide fractions, multiply the first number by the reciprocal of the second (2/3's reciprocal is 3/2 and 5/8's reciprocal is 8/5)

3/8 ÷1/7

= (3/8)*(7/1)

then multiply the numerators together and put them over the denominator

=21/8

= 2 and 5/8

16

step-by-step explanation:

2 x 40 = 80

80/5

= 16

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
