It would be 1/7 since you essentially are dividing by 7 to cancel out the original scaling.
Step one is to take 2.76 x 15. That will give us the total cost. That is 41.40. Next, we need to divide 41.40 by 2. So in total, it will save you 20.70.
You work out the price of each share:
$2500 ÷ 125 = $20 each
10% of that is $2, which added on means the share is worth $22
Hope it helps:-)
Answer:
9/20 yes, 4/15 not. See below
Step-by-step explanation:
Pick 9/20 and multiply numerator and denominator by 5:
9/20 = 45/100
We know that if we divide a number by 100 we need to move the coma as two places left, so:
9/20 = 45/100 = 0.45
And this is a terminal decimal as we know where it ends.
On the other hand if we pick 4/15 let try to divide it (here I will do it 'manually'):
4 |_ 15
we can divide 4 by 15, so we use 40 and begin with a comma
40 |_ 15
0.
15 enters 2 times in 40 with a rest of 10, so:
40 |_ 15
30 0.2
100
100 divided by 15 is 6 and we have 10 as rest again, and again and again...
40 |_ 15
30 0.266.....
100
100
....
So, we will have 0.266666666666666 infinitely. The decimal for 4/15 is non terminating and is 0.26666666666666666...
