Whats 4 1/12-1/2 ASAP PLEASE

Step-by-step explanation:

1 - multiply the 1/2 out to make the denominators the same (Ignore the 4 for now)

To make 2 equal 12 you multiply by 6 and what you do to the bottom you do to the top.

2 - Now solve

Now we need to know what 4 1/12 - 6/12 equals.

1-6 is -5 so we will take out of the whole number to continue this subtraction

3 12/12 - 5/12

After subtracting that out we're left with

3 7/12

Hope this helps :)

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
