Answer:
9 ml
Step-by-step explanation:
The Pediatrician prescribes 5 milliliters of cough syrup for every 25 lb of child weight.
Now, the weight of Jocelyn is 45 lb.
If the rate of prescribing the cough syrup in ml per weight of patients remains constant,
Then we can use the unitary method to get the amount of cough syrup prescribed by the Pediatrician for Jocelyn, and that will be
ml. (Answer)
5/7
6*5/6*7
30/42
30/42 = 30/42
Yes, 5/7 and 30/42 form a proportion.
868 is about 870, and 28 is about 30, so your expression would be 870 divided by 30 which would be 29 and the actual answer is 31, so your estimate would be close to your actual answer.
