Please HEl m! I have less than 10 minutes! Add:
A. 2 1/5 + 3 1/10
B. 472 2/5 + 312 3/4

A) 5  3/10

B) 785 3/20

Step-by-step explanation:

Hope this helps <3

you find a common denominator and then simplify all fractions to that common denominator. then, you add them up!

2 1/5 + 3 1/10

5 can fit into 10 twice so it becomes...

2 2/10 + 3 1/10 which equals

5 3/10

472 2/5 + 312 3/4

5 times 4 is 20

472 8/20 + 312 15/20

there is a remainder of 3 for the fractions so you put it over 20.

785 3/20

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
