What is -7/10 divided by 2/5 simplified

-7/4

Step-by-step explanation:

When dividing any numbers where one or more terms are fractions, we can use the process of KFC.

KFC:

K- keep the first

F- flip the second

C- switch to multiplication

So solving though with KFC:

-7/10 / 2/5

Keep the first:

-7/10 / 2/5

Flip the second:

-7/10 / 5/2

And change to multiplication:

-7/10( 5/2 )

Solve:

-7(5) = -35

10(2) = 20

-35/20

Simplify:

To simplify -35/20 we can divide each number by 5

-35/20

-7/4

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
