7 out of 24 is made by other companies because you need to find a common denominator for all of the numbers which is 24. 1/3 times 8 is 8/24, 1/4 times 6 is 6/24 and 1/8 times 3 is 3/24. Then add all of those fractions and you get 17 then subtract 24 by 17 to get 7 out of 24 as your fraction. Hope this helps!
Answer:
Yes, all three of them are proportional
Step-by-step explanation:
First, let's simplify them all the way:
10/45 = 2/9
20/90 = 2/9
6/27 = 2/9
All three of these ratios simplified down to their simplest form are 2/9, meaning that they are all proportional.
1:4 = 2:8
1:3 = 2:6
2:3 =4:6
1:12 = 4:48
Hope this helps!!
Is it adding or subtracting
Answer:
(x + 5)^2 = (5 - 3)^2
Step-by-step explanation:
Given the equation;
x^2 + 10x + 22 = 13
We have;
x^2 + 10x = 13 - 22
x^2 + 10x = -9
Adding half of 10 to both sides and completing the square as usual, we have;
(x + 5)^2 = 5^2 + (-9)
(x + 5)^2 = (5 - 3)^2
