15/x = 5/6

Plz help me solve this proportion of multiplication plz help

Step 1: Cross-multiply.

15 /x = 5 /6

(15)*(6)=5*x

90=5x

Step 2: Flip the equation.

5x=90

Step 3: Divide both sides by 5.

5x /5 = 90 /5

x=18

x=18

x=18

Step-by-step explanation:

divide 15 by 5/6= 15 times 6/5, simplify, 3 times 6, simplify, 18

give the other person brainliestt

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

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
