convert the fraction 12/20 to a decimal and to a percent!

12/20 = .6 = 60%

Step-by-step explanation:

12/20

We want a decimal

Decimal are over powers of 10

Divide the top and bottom by 2

12/2 = 6

20/2 =10

The fraction becomes 6/10 = .6

Now we need to convert it to a percent, which means out of 100

6/10 Multiply the top and bottom by 10

6*10 =60

10*10=100

60/100 = 60%

The decimal number is

The percentage number is

Step-by-step explanation:

we have

step 1

Convert to decimal

Simplify the fraction

Divide by 4 both numerator and denominator

step 2

Convert to percentage

we know that

To convert a number to percentage, multiply by 100

so

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.

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
