Question 1: Assume that y varies inversely with x. If y=9 when x=7, find y when x=2. Enter in any fractions using a / (e.g. "1/2

" is the same as 12 and 1 1/2 is the same as 112).
Question 2:Assume that y varies directly with x. If y=9 when x=−3, find x when y=6. Enter in any fractions using a / (e.g. "1/2" is the same as 12).

How many 2/3 's make up 4 1/5
miskamm [114]

Answer:

6³/₁₀

Step-by-step explanation:

Number of bits = Total amount/Size of each bit

                         = (4⅕)/(⅔)

Convert the mixed number to an improper fraction

No. = (²¹/₅)/(⅔)

Invert the denominator and change division to multiplication

No. = ²¹/₅ × ³/₂

Multiply numerators and denominators.

No. = ⁶³/₁₀

Convert the improper fraction to a mixed number.

No. = 6³/₁₀

It takes 6³/₁₀ ⅔s to make up 4⅕.

Allie bought a 5-pound bag of trail mix. She gave 12 ounces of trail mix to Justin. Then she put the rest of the trail mix into
trapecia [35]
To solve this problem, you will first want to convert 5 pounds into ounces. To do this, first determine how many ounces is in 1 pound.

There are 16 ounces in 1 pound, so to convert 5 pounds into ounces, you simply have to multiply 5 × 16. This will give you 80 ounces total.

Allie give 12 ounces away, so you must first subtract 12 ounces from your total (80 ounces). 80 - 12 gives us 68 ounces.

Allie then divides the trail mix up into 4 ounce portions. To figure out how many small bags she can make, you simply divide your new total (68 ounces) by 4. 

68 ÷ 4 = 17

Allie made 17 small bags.
