Try thinking of it as translating English to Math language:
Write out the English sentence. Below it, start by translating the words you can translate. For instance, under the word "times," write a multiplication sign.. Under the word "decreased" write a minus sign. The word "number" is your mystery number, often referred to as x. "Is" would generally be an equal sign, but here your word problem says "is at least". Can you figure out how you might depict that in Math language?
