In order to know how much of the 3/8 is in the 1/4, you calculate the quotient between 1/4 and 3/8, just as follow:
1/4 ÷ 3/8
you can convert the previous quotient into a multiplication by inverting the second fraction:
1/4 ÷ 3/8 = (1/4) x (8/3) = 8/12 = 2/3
Hence, 2/3 is what 3/8 is in 1/4
Answer:
The first one lol
Step-by-step explanation:
Answer:
The radius of the circle is 3.5 inches.
Step-by-step explanation:
The radius is half the diameter:R= 1/2 d
Substitute the value of d (7 inches) in the formula to find r:
r= 1/2 x 7 in
r= 3.5 in
Let 
be the number of liters of the 10% solution she needs to use. She'd end up with a 6% solution with a volume of 
liters. The starting solution contains 0.04*9 = 0.36 liter of salt. Each liter of the 10% solution contributes 0.1 liter of salt, so that
Solve for :
so Mayra needs to add 4.5 liters of the 10% solution.
The answer is A I think sorry if I’m wrong
