2) Represent the ratio 7 : 18  in two other ways

Explanation

The ratio 7:18 can be represented in two other ways as 14:36 and 21:54. This is because the ratio can be multiplied or divided by the same non-zero number to get equivalent ratios. In this case, multiplying 7 and 18 by 2 gives 14 and 36, and multiplying by 3 gives 21 and 54.

4) Which ratio is equal to 100 : 20?

Explanation

The ratio 10:2 is equal to 100:20 because both ratios can be simplified to 5:1. This means that for every 5 units in the first term of the ratio, there is 1 unit in the second term. So, if there are 100 units in the first term, there will be 20 units in the second term, resulting in the ratio 100:20.

Explanation

Leroy can lay 144 bricks in 3 hours, which means he can lay 48 bricks in 1 hour (144 divided by 3). To find out how many bricks he can lay in 7 hours, we can multiply the number of bricks he can lay in 1 hour (48) by the number of hours (7), which gives us 336 bricks. Therefore, the correct answer is 336.
