How do i solve this2/3 divided by 8/7 =

Answers

2/3 / 8/7 flip the second fraction and multiply straight across

2/3 x 7/8 2 x 7 = 14

3 x 8 = 24 so you have 14/24 if you need to simplify, since both numerator and denominator are even so divide by 2. Which gives you 7/12

Hope this helps you :)

To solve that you're gonna have to multiply 2/3 by the reciprocal of 8/7 which is 7/8.

2/3 * 7/8 = (2 * 7)/(3 * 8)

14/24 reduces to 7/12 or .5833

One group of people purchased 10 hot dogs and 5 soft drinks for $35. Another group purchased 7 hot dogs and 4 soft drinks for $25.25. What is the cost of a single hot dog? A single soft drink?

Answers

10 H + 5 D = $35    times all by 4 40 H + 20 D = $140.00
7 H + 4 D = $25.25 times all by 5 - 35 H - 20 D    = -126.25 and subtract
Subtract 5 H = $13.75
Divide by 5 to find price of one hot dog H = $2.75

10 ($2.75) + 5 D = $35 input cost of one hot dog into first equation
   $27.50 + 5 D = $35.00
- $27.50 = -$27.50
   5 D = $ 7.50 divide by 5 so one drink is $1.50 then go back and check

What is the value of x in the equation x-2/3 + 1/6 =5/6 ?

Answers

x is a negative one (-1). The negative one makes it so that the -2/3 is a positive when they multiply.

So in this problem we can see that 2 out of 3 of the fractions have a denominator of 6. One of the fractions (2/3) has a denominator of 3. But we can make the denominator 6 by multiplying it by 2!

Now the equation is:

x - 4/6 + 1/6 = 5/6

So now let's solve for x!

x - 4/6 + 1/6 = 5/6

x + 1/6 = 9/6 (Addition property of equality)

x = 8/6 (Subtraction property of equality)

Now we divide...

8 divided by 6 equals 1.33

Now if we plug that into the equation as 1 and 1/3...

1 and 1/3 - 2/3 + 1/6

2/3 + 1/6

4/6 + 1/6 = 5/6

So that means your answer is decimal 1.33 or mixed fraction 1 and 1/3
