Remark
What the question is saying is that you are setting up a proportion. Ordinarily a child would require 125 mg be put into 5 mL of liquid. This child is special and only requires 100 mg. How many mL are needed?
Proportion
125 mg : 5 mL :: 100 mg: x
Solution
125 / 5 = 100 / x Cross multiply
125x = 500 Divide by 125
125x/125 = 500/125 Do the division
x = 4
Answer
100 mg would be put in 4 mL of liquid
you cant really predict how many bagels will be sold the next morning because of different scenarios but mathematically speaking if you compare plain bagels to total bagels you get 3/15 so if you multiply the denominator by 1 1/4 to get twenty as the denominator then you have to do the same to the numerator to get a fraction of 3.75/20 or roughly 3-4 plain bagels sold
No it is no isosceles triangle because there are no two measures the same
