Please help-
And please explain if you know how to-

1 is 2/44=40/88

2 is 24/50=48/25

3 is 50/30=100/60

4 is 41/20.5=19/2

Step-by-step explanation:

your just multiplying or dividing by 2

pls mark braliest

1: 880, 2: 24, 3: 30, 4: 82

Step-by-step explanation:

1: If we divide by 2 we get 20. Then multiply 44 x 2 = 880

2: 25 is half of 50. So then, we divide 48 by 2 = 24

3: 50 x 2 = 100. Then, we divide 60 by 2 becasue it is reverse; 60÷2 = 30

4: 38 divided by 19 = 2. Then we multiply 41 by 2 becasueit is reversed. 41 x 2=82

- "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."
