Answer:

18, 21 and 36

Step-by-step explanation:

The best way to solve this is to format the question as a series of equations, then solve them.

Let x = the smallest number, y = the middle number and z = the largest number:

z = 2x

y = x + 3

x + y + z = 75

We can now substitute the values of y and z in terms of x into the equation x + y + z = 75:

x + (x + 3) + (2x) = 75

Now, solve:

x + x + 3 + 2x = 75

4x + 3 = 75

4x = 72

x = 18

Therefore, the smallest number is 18, the middle number is 21 and the largest number is 36.

Which is bigger, 7/8" or 9/16"?
Iteru [2.4K]
7/8 and 9/16

7*2/8*2 = 14/16

14/16 and 9/16

Now since we have a common denominator, we can compare the numerators.

14/16 is greater, so 7/8 is greater than 9/16

Answer: 7/8 is bigger
