Question

4)

A piece of cable 8.5 cm long weighs 34 grams. What will a 29.75-cm length of the same cable weigh?
5) Jack runs 1 1/3 mile for every 3/4 mile that marco runs. if marco has run 5 miles, how far has jack run?
6)
7) find the value of n
3/4 over 1 1/3 = n over 5 2/3
8) a docter sees each of her patients for 25 minutes during a typical appointment. how many patients can she see in a typical 7 1/2 hour day?

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
