Question

Create a proportion using the form %/100 = is/of to represent the following word problem.

78% of what number is 42?

Answer 1

To create a proportion in the form %/100 = is/of for the problem "78% of what number is 42?", we need to identify the components of the proportion:

• % is 78
• is is 42
• of is the unknown number we are trying to find

So, we can set it up as:

\[ \frac{78}{100} = \frac{42}{x} \]

where \( x \) represents the unknown number we are looking for.

Thus, the final proportion is:

\[ \frac{78}{100} = \frac{42}{x} \]
