What is 9 2/5-8 1/3 I need to know for math tomorrow

patriot [66]

Answer:

$1\frac{1}{15}$

Step-by-step explanation:

Let's use a start by using common denominators. $9\frac{2}{5} = 9\frac{6}{15}$ and $8\frac{1}{3} = 8 \frac{5}{15}$

Now, replace the original equation with the common denominators. $9\frac{6}{15} - 8\frac{5}{15}$

Solve! $9\frac{6}{15} - 8\frac{5}{15} = 1\frac{1}{15}$

The perimeter of a rectangular field is 302 yards. If the width of the field is 65 yards, what is its length?

Molodets [167]

Answer:

L= 86 yards

Step-by-step explanation:

Perimeter = 2length + 2width

So,

302= 65(2) + 2(L)

302= 130+2L

-130

172=2L

Length= 86
