Answer:
5
Step-by-step explanation:
A) Divide and compare in decimal form -
9/25 = 0.36
4/6=2/7 = 1/4 = 0.25
0.6... > 0.25
B) Fraction to decimal conversion:
4/16 = 2/8 = 1/4 = 0.25
Use long decision or a calculator - 1 divided by four
C) Again, 9/25 = nine divided by twenty-five = 0.36
% Science class)
0.36 = 36%
Move decimal place to right twice and place “%” at the end.
Answer:
640
Step-by-step explanation:
Subtract the 7 from both sides,
you are left with
11=y
Ok, to solve this first you have to set up your proportion:
9/150=x/230
/ is a fraction
x= the number of vials it will take to treat 230 patients
in order to solve this, you have to cross multiply:
9 x 230= 2070
150 · x= 150x
so you get 150x=2070
then divide 2070 by 150
2070/150= 13.8
so it would take 13.8 vials of medicine to treat 230 patients
