We can calculate the mmc between 8 and 12

8, 12 | 2

4 , 6 | 2

2 , 3 | 2

1 , 3 | 3

1, 1 | 1

mmc = 2 × 2× 2×3

mmc = 24

24 ÷ 8 = 3

And

24 ÷ 12 = 2

3/8 + 5/12 = ( 3× 3+ 5×2)/24

= (9 + 10)/24

= 19 / 24

Answer = 19/24

Another way of calculating would be to multiply the denominator and multiply the extremes.


3/8 + 5/12 = ( 3 × 12 + 8×5)/8×12

= ( 36 + 40)/96

= 76/96

Division by 2

= 38 / 48

Division by 2

= 19 / 24

I hope this has helped.

Which table represents a linear function?​
Andrew [12]

Answer:

The first table is the only table representing a linear function.

Step-by-step explanation:

<em>" You can tell if a table is linear by looking at how X and Y change. If, as X increases by 1, Y increases by a constant rate, then a table is linear. You can find the constant rate by finding the first difference. This table is linear."</em>
