A notebook is 3/10 off the original price. How could this be written as a decimal? What percentage is the discount?

A decimal: 0.3     A percentage: 30%

Step-by-step explanation:

To calculate the decimal:

3/10=0.3

Three divided by 10 is 0.

After writing the zero put a little dot beside it.

Then you add a little zero to three to make it 30

Then it becomes 30 divided by 10 and the answer is three so the decimal is 0.3

To calculate the percentage:

You can use the decimal. So we say 0.3 multiplied by 100 because a percentage is out of 100.

The answer is 30%

- "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."
