What is 5/6 divided by 1/7?
skelet666 [1.2K]

Answer:

5\frac{5}{6}

Step-by-step explanation:

To divide fractions, we multiply the first fraction by the <u>reciprocal </u>of the second fraction. (Seven over one)

\frac{5*7}{6*1} =\frac{35}{6}

Now, we convert the fraction into a mixed fraction.

\frac{35}{6}=5\frac{5}{6}

<em>The quotient of 5/6 and 1/7 is 5 5/6</em>

2. At the local park, there is an annual fair that
mafiozo [28]

Answer:

132 children and 88 adults

Step-by-step explanation:

let x represent the amount of kids and y represent the amount of adults.

since the problem says there was a total of 220 people at the fair an equation can be made

x+y=220

the problem tells that each childrens ticket was 1.5$ and each adult ticket was $4 and that a total of $550 was made that day, we can use the knowledge to make an equation:

1.5x + 4y = 550

using the equations we can make this systems of equations:

1.5x + 4y =550

x + y =220

solve the systems of equations by subracting y on both sides of th bottom equation:

x=220-y

since x is equivant to 220-y it can be substitued for x in the first equation to make this:

1.5(220-y)+4y =550

--solve for y--

y=88  - there were 88 adults

substute 88 for y in the second equation

x+88=220

--solve for x--

x=138 - there were 132 children
