Arithmetic
That is the study of sequences of numbers
The naming of similar triangles has corresponding vertices in the same order in the name. That means segment QS corresponds to segment AC. We note that QS = 6 cm is 1/10 the length of AC = 60 cm.
Side AB is given as 50 cm, so the corresponding side QR will be 1/10 that value.
... QR = 5 cm
126 1/4 = 126 3/12 = 125 15/12
- 78 2/3 = - 78 8/12 = - 78 8/12
--------------------------------------...
47 7/12
1) Find the lowest common denominator (LCD) for the fractions. In this case, 12 is the LCD.
2) Rewrite the fractions 1/4 and 2/3 using 12 as the denominator (second column). You get 3/12 and 8/12.
3) Since it's confusing to subtract 8/12 from 3/12, you need to borrow one from the 126. Doing so is the same as taking 12/12 from 126. This changes to 125, and the 12/12 adds to the 3/12 making it 15/12.
4) Subtract 8/12 from 15/12 to get 7/12.
5) Subtract 78 from 125 to get 47.
6) The answer is 47 7/12.
