Answer:
3 to 12 and 1 to 4:
Step-by-step explanation:
3 to 12 would be = 3:12
1 to 4 would be = 1:4
Since ratios can also be fractions, think of it this way. 3:12 as 3/12, and 1:4 as 1/4.
Now, if you simplify, you will see they are equivalent to each other,
3/12 = 1/4
Answer:
400milliliters
Step-by-step explanation:
Let x=ml of 30% solution B used in resulting mixture.
800+x=ml of resulting 30% solution
40%(800)+10%x=30%(800+x)
Then we can simplify the expression
0.4(800)+0.10x= 0.30(800+x)
320+0.10x=240+0.30x
80=0.20x
x= 400milliliters
Therefore, 400milliliters of 10% solution B used in resulting mixture.
