Number 1 wants you to set up proportions so four numbers equal to 2/1 would be: 6/3 8/4 10/5 12/6, and so on. I'm not sure what they're asking when they say the sum of the first two numbers is equal to 4.8
Answer: $9.20
Step-by-step explanation: To get the answer, you add both the cost and multiply it by .15. Then you add the product to the number you got adding the cost of the food.
80/2= 20 then take away the extra 20 from the math for dance and you have the answer... 20 get it?
Nick is incorrect because he subtracted 3-1 and 3-2. The answer is 1 3/4 It is that distance because 3 2/4-1 3/4=1 3/4.
When you divide two fractions, you're actually multiplying one of them by the reciprocal of the other. First, find the reciprocal of the second fraction by flipping it upside down. Then, multiply it by the first fraction. (Numerator x numerator and denominator x denominator)
![\frac{-7}{12}](https://tex.z-dn.net/?f=%20%5Cfrac%7B-7%7D%7B12%7D)
÷
![\frac{2}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B3%7D%20)
Replace the second fraction with it's reciprocal
![\frac{-7}{12}](https://tex.z-dn.net/?f=%20%5Cfrac%7B-7%7D%7B12%7D)
x
![\frac{3}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B2%7D%20)
Multiply (-7 x 3 and 12 x 2)
![\frac{-21}{24}](https://tex.z-dn.net/?f=%20%5Cfrac%7B-21%7D%7B24%7D%20)
Both 21 and 24 are divisible by three, so divide them by 3
