16. What is the difference if the quotient of 8/13 and 4 is subtracted from
the product of 1 3/4 and 8/21 ?​


Sagot :

Answer:

= -20/39

Step-by-step explanation:

(8/13 / 4) - (1 3/4 x 8/21)= 20/39

(8/13 / 4)

8/13 / 4 =

8/13 / 4/1 =

8/13 x 1/4= 8/52  lowest term 8/52 / 4 = 2/13

(1 3/4 x 8/21)

1 3/4 x 8/21 = 7/4 x 8/21 = 56/84 lowest term 56/84 / 28= 2/3

2/13 - 2/3

2/13 - 2/3= 6/39 - 26/39 = -20/39

= -20/39
