Monica has a 24
24
-inch square frame. there are 4
4
equal sides. she paints 34
3
4
of one side of the frame blue.

what fraction of the frame did monica paint blue?

The fraction of frame did Monica paint blue is  

Step-by-step explanation:

Given as :

The area of square frame = A = 24 square inches

Monica paint of one side of the frame blue

Let the measure of one side of frame = x

So, From Area of square

Area = side × side

Or, A = x × x

Or, x ² = 24

∴  x = = 2

So, Measure of each side = x = 2

Now, As Monica paint of one side of the frame blue

So, The painted part = ×  2

∴ The painted part = ×

I,e The fraction of painted blue =

Hence, The fraction of frame did Monica paint blue is  Answer

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
