Answer:

= #63%#

Explanation:

AS a fraction, #12.60/20# gives the answer #0.63.#

In decimal form this means #63/100# which is #63%.#

To get to the percentage format in one step, we note that the number needs to be 100 times bigger. However we may not just multiply by 100, so we multiply and divide by 100, which means the same as multiplying by 1.

#12.60/20 xx 100 div 100 =12.60/20 xx 100/100 =12.60/20 xx 100%#

#:. 12.60/20 xx 100%#

= #63%#

or

#12.60/20 xx5/5 = 63/100 = 63%#
