Maria multiplied by 1 to rename 1/4 as hundredths. She made factor pairs to equal to 10. Use her method to change one eighth to an equivalent decimal.

Step-by-step explanation:

Marias idea was to make a factor of ten so that she can easily divide it

i.e

¼=½×½

note that, ½=5/10

Therefore,

¼=(5/10) ×(5/10)

¼=(5×5)/(10×10)

¼=25/100

¼=0.25

Apply are method to one eighth

⅛=½×½×½

Also note that, ½=5/10

Therefore,

⅛=(5/10) ×(5/10)×(5/10)

⅛=(5×5×5)/(10×10×10)

⅛=125/1000

⅛=0.125

She can do this way, or she might have did this

¼=½×½

Multiple both the denominator and numerator by 5 i.e 5/5 to turn the denominator to 10.

Note, 5/5 is a factor 1

¼=½×½×5/5×5/5

¼= (5×5)/(2×5×2×5)

¼=(25)/(10×10)

¼=(25/100)

¼= 0.25

Also applying to one eighth

⅛=½×½×½

Multiple both the denominator and numerator by 5 i.e 5/5 to turn the denominator to 10.

Note, 5/5 is a factor 1

In the case we have three 2 so we need three of 5/5

⅛=½×½×½ ×5/5×5/5×5/5

⅛= (5×5×5)/(2×5×2×5×2×5)

⅛=(125)/(10×10×10)

⅛=(125/1000)

⅛= 0.125

step-by-step explanation:

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
