Answer: 
This is the same as writing (n-m)/n
Don't forget about the parenthesis if you go with the second option.
==================================================
Explanation:
The probability that she wins is m/n, where m,n are placeholders for positive whole numbers.
For instance, m = 2 and n = 5 leads to m/n = 2/5. This would mean that out of n = 5 chances, she wins m = 2 times.
The probability of her not winning is 1 - (m/n). We subtract the probability of winning from 1 to get the probability of losing.
We could leave the answer like this, but your teacher says that the answer must be "in the form of a combined single fraction".
Doing a bit of algebra would have these steps

and now the expression is one single fraction.
Answer: 50,380m
Step-by-step explanation:
190m * 270m = 51,300m
23m * 40m = 920m
Because the barn is in the field, we subtract the barn's area from the field's area, which leaves us with
51,300m - 920m = 50,380m

$1.25 for a fruit tart
3.5 multiplied by 52 would be 182, and that is the 52nd term in that sequence.
Answer:
$31.44
Step-by-step explanation:
According to the word problem, Peter has a coupon for 15% OFF.
This means the price will reduce by 15%.
To solve this, first, change the percentage (15%) to decimal form.
To do this, divide the percentage by 100.
15 / 100 = 0.15.
0.15 is the decimal form of 15%.
Next, multiply the decimal form of the percentage by the price.
36.99 x 0.15 = 5.5485
Lastly, subtract the product from the original price.
36.99 - 5.5485 = 31.4415
In this case, the product goes above the hundredths place.
So we must round 31.4415 to the hundredths place.
31.4415 ≈ 31.44
Therefore, the sneakers are $31.44 after the discount of 15%.
