1 5/8 divided by 3/8? Show your work pls.
Dafna1 [17]
Change mixed fraction to improper fraction and also the second fraction has to be reciprocal

Ex- 3/8= 8/3

So now the problem is

13/8*8/3= 13/3 (because you cross divide) Now, turn into fraction

Divide

13 divided by 3= 4 1/3

So your final answer is 4 1/3

May someone help me please, I'm having alot of trouble. im giving poitns
saveliy_v [14]

Answer:

24 with a remainder of 1

Step-by-step explanation

so first you have to bring down the 3 so it is next to the six, and then you divide 36 by 15 and that equals 2. So you right a 2 on top. Then you have to multiply 2 and 15 and that equals 30 so you put a 30 below the 36. After you subtract, it equals 6 then you bring down the 1. Now you divide 61 and 15. The answer is 4 so you put a 4 on top next to the 2. After that you multiply 15 by 4 and that equals 60. You subtract 60 from 61, and you are left with a remainder of 1

Skylar and her children went into a movie theater and will buy bags of popcorn and pretzels. Each bag of popcorn costs $8 and ea
Masja [62]

Answer:

8b+3.25p\leq 80

Step-by-step explanation:

Each bag of popcorn costs $8

Each pretzel costs $3.25.

  • The total cost of b bags of popcorn =$8*b=$8b
  • The total cost of p pretzels purchased =$3.25*p=$3.25p

Skylar has a total of $80 to spend on both items. This means that she can either spend less than or exactly $80.

i.e Total Cost \leq \$80

Skylar's Total cost on popcorns and pretzels =8b+3.25p

Therefore:

8b+3.25p\leq 80

Therefore, an inequality that would represent the possible values for the number of bags of popcorn purchased, b, and the number of pretzels purchased, p will be:

8b+3.25p\leq 80
