What is 5 and 4/5 plus 1 and 1/8? . thx

First make the mixed numbers into improper fractions and then find the LCD then combine which will give you the answer of 277 / 40

You can find the area of a rectangle by multiplying the length and height. so multiply 1/2*7/4(which is the simpler version of 1 3/4) and you get 7/8 as your answer.

B. because the 7 represents "seven times", x represents "a number", 12 represents "plus twelve", and -4 represents "minus four"
