Step-by-step explanation:

1/2 , 5/11

Convert into same denominator using lcm: which is 22

1/2 = 11/22

5/11 = 10/22

11/22 > 10/22

1/2 > 5/11

4/9 , 9/20

Lcm: 180

4/9 = 80/180

9/20 = 81/180

80/180 < 81/180

4/9 < 9/20

a) 0,0; 1,1; and 2,2

step-by-step explanation:

these have the exact same coordinates, thus they are the correct function.

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.
