Darius buys a bottle of a chemical solution that contains 70, percent alcohol. The bottle contains 500 milliliters of solution. How many milliliters of alcohol are in the solution?

There are 350 milliliters of alcohol in the bottle

Step-by-step explanation:

Step 1

The amount of solution  contained in the bottle = 500 millilitres

The percentage of alcohol contained in  the bottle  of 500 millilitres= 70%.

Therefore  amount of alcohol in the solution is  70% of 500 millilitres

Step 2 --- Solving we have

70/100 × 500 =  0.70 x 500 =  350 ml

There are 350 millilitres of alcohol in the bottle.

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

b
