Aconstruction crew has just finished building a road. the road is 12 kilometers long .if the crew worked for 5 2/5 days, how many kilometers of road did they build each day?

The build 2 kilometers each day

Step-by-step explanation:

Set up an equation

The road is 12 kilometers long and it was worked on for 5 days.

So, to set up the equation, divide 12 by 5

 Make 5 into an improper fraction

Multiply 5 by 5, then add 2

You can't divide a number by a fraction, so you kcf (keep it, change it, flip it)

So keep the 12, change the division to multiplication, flip

12 x Multiply straight across

x =

Simplify

=  The top and the bottom both have 3 in common

Then make into a mixed number

2 9 goes into 20 2 times and has a remainder of 2

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
