Answer:

15 ml

Step-by-step explanation:

We will use a proportion to solve this problem. A proportion is setting a ratio equal to another ratio.

We start with the known ratio.

ratio of A to B = A/B = 3/2

Now we write the ratio that contains A as an unknown.

We want the amount of solution B to be 10 ml. Let the amount of solution A be A.

The ratio is A/10.

A/10 and 3/2 must be equal.

A/10 = 3/2

When you set two ratios equal, you have a proportion.

Now we solve the proportion for A.

Cross multiply.

2 * A = 10 * 3

2A = 30

A = 15

Answer: 15 ml

tiny-mole [99]

Answer:

4 pound

Step-by-step explanation:

From the question :

2 gallons of water = 8 pound bag

Number of pound bag per gallon of water ;

Let the number of pound = x

Using cross multiplication, we'll have :

2 gallons = 8 pounds

1 gallon = x pounds

Cross multiply

2x = 8

x = 8 /2

x = 4

Hence, 1 gallon of water mixes 4 pound bag of concrete.
