There are many ways to solve number 5 as it is just an reduce/enlargement of equidistant fractions
The first method that came up to my mind is just dividing denominators.
For A) you can do 72 divided by 18 which would give you 4. Then you can divide the given numerator with the answer you got from dividing the denominators. This would be 8 divided by 4 which would give you two. This means that 2/18 is equal to 8/72. You can check by simplifying the fraction. Both 2/18 and 8/72 equal 9 when simplified, therefore correct.
You can use this method for b, either use a calculator because of the decimals or just remove the decimals and replace them later. Make sure when you use this method, you are always dividing the bigger number. So in B you would do 40.3 divided by 12.4
By cutting away identical squares from each corner of a rectangular piece of cardboard and folding up the resulting flaps, an open box may be made. If the cardboard is 12 in. long and 10 in. wide, find the dimensions of the box that will yield the maximum volume. (Round your answers to two decimal places.)
in (smallest value)

in (largest value)
The way you add 4 digit numbers is by taking each place value and adding them each together. One's get added with ones, tens get added with tens and so on. For example, to add 1864+7528, you would first start off with adding 4 and 8 which gives you 12. The 2 will go under the equation and the 1 will travel to the tens place. Next, 2+6 which is 8 and then add the 1 from 12 which gives you 9. Then, 8+5 which is 13. Again, the 3 will go under the equation and the 1 will travel to the thousands place. Finally, 7+1 which is 8 and then add the 1 from 13 which gives you 9. The sum should be 9392.
