neonofarm [45]

Answer:

1/3

Step-by-step explanation:

Left over pie=5/8

Payton eats=1/8 of the left over pie

Joy eats =1/6 of the left over pie

Total pie eaten by Payton and joy= 1/8+1/6

To add the fraction,

Find the lowest common multiple of 6 and 8 which is 48

Then,

divide 48 by 8 multiplied by 1 which is 6,

divide 48 by 6 multiplied by 1 which is 8

We have,

=6+8/48

=14/48

=7/24

Total pie eaten by Peyton and joy=7/24

Total pie left(after Peyton and joy share)= Total left over- total pie eaten by Peyton and joy

=5/8-7/24

=15-7/24

=8/24

=1/3

A rectangular garden has an area of 37 square miles. If its length is 28 miles, what is its width?
Semmy [17]

Answer:

\frac{37}{28} miles

Step-by-step explanation:

Use the area formula, A = lw, where l is the length and w is the width.

Plug in the area and length into the formula, and solve for w:

A = lw

37 = 28w

37/28 = w

So, as a fraction, the width of the garden is \frac{37}{28} miles
