You are making up your own mix of concrete to patch a set of stairs. In order to have the proper mix, you need to mix 1 part of Portland cement with 2 parts of sand and 3 parts of gravel.

A. How many total parts are in one batch of concrete?
B. You make a mix with 4 parts of sand. How many total parts of cement, sand, and gravel are in your mix?

Is A:6
and
B:12

A: Well, if you mix 1 part of cement with 2 parts of sand and 3 parts of gravel, you'll end up with a total of 6 parts in one batch of concrete. It's like a party in a wheelbarrow!

B: Ah, you like to go big with 4 parts of sand! In that case, your mix will have a total of 9 parts of gravel and 4 parts of cement, along with the 4 parts of sand. That adds up to a grand total of 17 parts. It's like throwing a concrete bash with extra sand to keep it groovy!

A. Yes, the total number of parts in one batch of concrete is indeed 6.

B. No, the total number of parts in your mix with 4 parts of sand is not 12. To find the total number of parts, you need to consider the ratio given for the mix. Given that the ratio is 1 part cement : 2 parts sand : 3 parts gravel, the total parts in the mix would be:

Cement: 1 part
Sand: 2 parts
Gravel: 3 parts

Therefore, the total number of parts in your mix would be 1 + 2 + 3 = 6.

To solve these problems, we need to add up the number of parts of each component required in the mix.

For the first question, the mix consists of 1 part Portland cement, 2 parts sand, and 3 parts gravel. To find the total number of parts in one batch of concrete, we add these numbers together:

1 part cement + 2 parts sand + 3 parts gravel = 6 parts

Therefore, the answer to question A is 6.

For the second question, you mentioned that the mix has 4 parts of sand. We still need to consider the other components - cement and gravel. According to the initial ratio, the mix is 1 part cement, 2 parts sand, and 3 parts gravel.

So, we have 4 parts sand along with 1 part cement and 3 parts gravel. To find the total number of parts in this mix, we add these numbers together:

1 part cement + 4 parts sand + 3 parts gravel = 8 parts

Therefore, the answer to question B is 8.

Right.
