Step-by-step explanation:
ooooh I loved these. ok. so if you have a set of lines like this, we will just use an "x" as an example for lines crossing. if you have 100 as the angle on the top, then the angle on the bottom will be exactly the same. the top and bottom are the same angle ALWAYS. the angles across from each other are the same. because brainly will timeout on me if I stop typing, I will post this and later I will post a picture of the first few finished as an example so you get what i'm talking.
7/8-4/5. When subtracting two fractions, we must have a common denominator. A common denominator is a factor in which goes into both 8 and 5.
1.) Common factor: 45. 45 goes into and 8 and 5. If we list out all the factors of 8 and 5, 45 will be the lowest common factor.
2.) We need to multiply by a number to get 45 for each denominator. We can a one-step equation to figure out what we need to multiply 8 by and 5 by to get 45.
X=the factor of 8 that will get us 45.
8x=45
8x/8=45/8
x=5.625.
Y=factor of 5 that will get us 45.
5y=45
5y/5=45/5
y=9.
3.) We now know that we need to multiply 8 by 5.625 and 5 by 9 in order to get 45 as the denominator for both fractions.
7/8x5.625-4/5x9
7/45-4/45.
4.) Whatever is done to the denominator must be done to the numerator.
7x5.625/45-4x9/45
39.375/45-36/45
5.) We now have common denominators, so we simple subtract the numerators ONLY. We DO NOT subtract the denominators.
39.375/45-36/45=3.375/45.
Therefore, 3.375/45 is your answer.
