Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Customer 1:

5 peanut butter biscuit = $3

Price per product sold :

Number Sold / price

= 5/3

Customer 2:

7 beef treats for $4.20

Price per product sold :

Number Sold / price

= 7/4.20

The cross product :

5/3 = 7 / 4.20

Cross multiply

5 * 4.20 = 3 * 7

21 = 21

Cross product of both = 21

What is 5/6 times 7/4

Answers

To solve this, we simply need to multiply the numerators and the denominators together.

$(5)/(6) * (7)/(4) = (5*7)/(6*4) = (35)/(24)$

Which is our final answer, as it cannot be simplified further.
$(5)/(6)$ times $(7)/(4)$ is $(35)/(24)$ .
Hope that helped! =)

First of all, we are not solving a fraction problem or it would have been 5^6 times 7^4. 5 divided by 6 times 7 divided by 4 is 1.4583
