What is the missing fraction for 1/6 1/8 1/4 ? /? = 1whole

can somebody solve this for me i have been asking this for the third time

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:

the height of the surface increases from the center out to the sides of the road

it is c!

5 + 8 +7 + 4 + 0 +1 = 25

step-by-step explanation:

it would be 3 ÷by 6 because the number on each side
