Answer:

The missing numerator is 2.

Step-by-step explanation:

when you plug in 2 as the missing numerator and simplify you get 18/35.

\frac{4}{5} -\frac{2}{7}=\frac{18}{35}

the subtraction turns into 28/35 minus 10/35 which equals to 18/35

4/5 - /7 =

4/5 - 2/7

5 * 7 = 35

7 * 4 = 28

5 * 2 = 10

28/35 - 10/35 = 18/35

Helen [10]

The Original price of the meal was $12.16.

Discount Percent is defined as the discount given on the product per hundred .

For Example . if there is 10% discount on a price of $100.

The final amount will be $90.

Final amount paid by Fiona = $8.25

percentage discount = 10%

Let the original amount be x.

According to the question ;

x - 10% of x = 8.25

x-\frac{10}{100} *x=8.25\\ \\ \frac{100x-10x}{100} =8.25\\ \\ \frac{90x}{100} =8.25\\ \\ x=\frac{8.25*100}{90}\\ \\ x=\frac{825}{90}  \\ \\ x=9.16

Since Fiona also had a discount coupon of  $3.

The original amount will be $9.16+$3=$12.16.

Therefore , The original price of the meal was $12.16.
