find the are of a rectangle that is 20 1/2in by16 3/7


simply your answer and type a mixed #

20+1/2 x 16+3/7
= (20x2+1)/2 x (16x7+3)/7
= 41/2 x 115/7
= (41x115)/(2x7)
= 4715/14
How many 14's fit as a whole into 4715? 336.
336+x/14
How much of the numerator is left? 336x14=4704 then 4715 -4704 = 11

336 11/14
