Divide the whole numbers:
2.04 / -2 = -1.02
When Dividing scientific notation, subtract the exponents from each other:
-9 - -5 = -9 +5 = -4
The answer becomes -1.02 x 10^-4
namely, how many times does 0.4 go into 6⅓? or 6⅓ ÷ 0.4.
first off, let's convert the mixed fraction to improper, and the decimal to a fraction . We can always convert the decimal to a fraction by simply <u>adding as many zeros on the denominator as there are decimals and lose the dot atop</u>, let's do so.
