Acertain drug is made from only two ingredients: compound a and compound b. there are 4 milliliters of compound a used for every 7 milliliters of compound b. if a chemist wants to make 671 milliliters of the drug, how many milliliters of compound a are needed?

answer:

there are 5 milliliters of compound a used for every 8 milliliters of compound b.

if a chemist wants to make 884 milliliters of the drug, how many milliliters of compound a are needed?

:

we know the ratio of a to b is 5: 8

let x = the multiplier

then

5x = amt of compound a

and

8x = amt of compound b

:

5x + 8x = 884

13x = 884

x = 884/13

x = 68 is the multiplier

therefore

5(68) = 340 millilters of compound a needed

:

:

confirm our answer. find the amt of b

8(68) = 544 ml of b

340 + 544 = 884

step-by-step explanation:

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
