Write two equivalent fractions for each 2/3
lutik1710 [3]

Not sure if you want an equivalent fraction for 2/3 or 2 and 3 so I will give both!

2 can be any fraction where the numerator is 2x larger than the denominator.

Example, 2/1, 4/2, 6/3, 8,4 etc.

3 can be any fraction where the numerator is 3x larger than the denominator.

Example, 3/1, 6/2, 9/3, 12/4 etc.

An equal fraction to the fraction 2/3 would be anything that has a numerator is 2/3x larger than the denominator.

Example, 4/6, 6/9, 8/12 etc.

Hope this helps. :)

Nancy’s nut store sells peanuts for $2 per pound and cashews for $10 per pound. The store sells a peanut - cashew mixture for $7
Gelneren [198K]

9514 1404 393

Answer:

  • 25 pounds cashews
  • 15 pounds peanuts

Step-by-step explanation:

Let c represent the number of pounds of cashews in the mix. Then 40-c is the number of pounds of peanuts. The total cost of the mix is ...

  10c +2(40 -c) = 7(40)

  8c +80 = 280 . . . . simplify

  c +10 = 35 . . . . . . . divide by 8

  c = 25 . . . . . . . . . . subtract 10

  40-c = 40-25 = 15 . . . . pounds of peanuts

25 pounds of cashews and 15 pounds of peanuts should be used in the mix.
