Margarita [4]

Given:

Total distance = $6\dfrac{1}{5}$ miles

Hiking before lunch = $2\dfrac{2}{3}$ miles

To find:

How much further does Sylvia have left to hike?

Solution:

Let x be the remaining hiking distance.

We know that,

Total hiking distance = Hiking before lunch + Remaining hiking distance

$6\dfrac{1}{5}=2\dfrac{2}{3}+x$

$\dfrac{(6\times 5)+1}{5}=\dfrac{(2\times 3)+2}{3}+x$

$\dfrac{30+1}{5}=\dfrac{6+2}{3}+x$

$\dfrac{31}{5}=\dfrac{8}{3}+x$

Isolate variable term.

$\dfrac{31}{5}-\dfrac{8}{3}=x$

$\dfrac{93-40}{15}=x$

$\dfrac{53}{15}=x$

It can be written as

$\dfrac{45+8}{15}=x$

$\dfrac{(3\times 15)+8}{15}=x$

$3\dfrac{8}{15}=x$

So, $3\dfrac{8}{15}$ miles left to hike.

Therefore, the correct option is C.

dimaraw [331]

Answer:

$8\frac{1}{8}$ ounces.

Step-by-step explanation:

Given

Number of rows of corn $=2\frac{1}{2}$ rows.

Seed required in each row is $=3\frac{1}{4}$ ounces.

So, total seed required to plant corn in $2\frac{1}{2}$ rows is

Number of rows of corn $\times$ Seed required in each row

$=(2\frac{1}{2})\times(3\frac{1}{4})\\\\\ Multply\ denominator\ to\ whole\ number\ part\ then\ add\ that\ number\ to\ numerator\\\\=\frac{5}{2}\times\frac{13}{4}\\ \\Divide\ 65\ by\ 8\ we\ have\ 8\ with\ reminder\ 1\\\\=\frac{65}{8}\\\\So,\frac{65}{8} =8\frac{1}{8}$
