Question

4)

Answer 1

You could use a ratio form for the first question

4)           8.5 : 34

         29.75 :   x                       x is the unknown

To find x, you must divide 29.75 by the length 8.5 to find the amount needed to be multipled by 34 grams, to find the total grams needed for the length of 29.75

29.75 / 8.5= 3.5             34 x 3.5 = 119 grams  , which is the answer to 4)

5) Same for this question, use the ratio form

         1 1/3 : 3/4                          5 / 0.75 ( 3/4) = 6.7

             x   :  5 miles                    6.7 x 1 1/3 = 8.91 Miles jack ran

6) ?? (Question not shown)

7) n = 0.6

8) 1 patient : 25 mins

   n patients : 7.5 hours

25 mins to hours = 0.4

1 : 0.4

n : 7.5           7.5 /0.4 = 18.75 ----> 19 patients
