Of the students in Marci's school, 5/9 have a pet. Of the students who have a pet, 12/25 have a dog. What fraction of the students in the school have a dog?

4 / 15

Step-by-step explanation:

Of all students ; 5/9 have a pets

Of the 5/9 who have a pet; 12 /25 have a dog

Fraction of the student in the school who have a dog;

12 /25 of fraction with pet

= 12 /25 of 5 /9

= 12 /25 * 5 / 9

= (12 * 5) / (25 * 9)

= 60 / 225

= 4 / 15

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
