<span>the ratio in which the sweets are distributed are 4:5:7.
total number of portions are 4 + 5 + 7 = 16.
we are told that Seth has 18 more sweets than Frank.
if we take the ratio of Frank to Seth its 4:7. Seth has 3 portions more than Frank. 3 portions are equivalent to 18 sweets. Therefore 1 portion is equal to 6 sweets. altogether there are 16 portions ,
therefore total number of sweets are 16 x 6 sweets = 96 sweets. they shared a total of 96 sweets</span>
Given: A cuboid with the dimesion below:
To Determine: The surface area of the cuboid
The formula for finding the surface area of a cuboid is given as:
From the diagram, it can be seen that
Substitute the given into the formula as shown below:
Hence, the surface area of the given cuboid is 130cm²

To check this yourself, you need the denominators to be the same to be able to easily compare the two.
For example, does 5/8 = 40/64?
1. Determine what you would need to do to the denominator in 5/8 to make it 64. (Multiply it by 8)
2. Find what fraction is equal to 1 with a denominator of 8. (8/8)
3. Multiply the fraction 5/8 by the one you just found (8/8), numerator times numerator, denominator times denominator.
4. Compare the answer with the second fraction.
It is important that when you multiply the denominator by any number you multiply the numerator by the same number. This is to preserve the fraction's value. This works because any number divided by itself is equal to 1, AND when you multiply any number by 1 (whether 1 is in the form of 1 or 4/4 or 8/8 or 234/234), the answer is always equal to the original number.
Another way to check would be to simply enter 1/2 into a calculator, write down the answer. Next enter 5/8 into a calculator. If the answers are the same, they are equal.</span><span>

As it is a straight line all the angles add up to 180 so 5s+18+48-a+8a-30= 180 so simplified 12a+36=180 then solve to get a=12.17 so then when u put 12.17 as a you get 5 * 12.17 +8 =78.85 then 48-12.17 which is clearly<78.85 then you do the final angle of 8*12.17-30 which is 67.36 so angle AOC is the biggest
