Question

fill in the blanks,
fractions equivalent to 7:1
77: blank

Answer 1

To find a fraction equivalent to \( 7:1 \) in the form \( 77: x \), you can set up a proportion:

\[
\frac{7}{1} = \frac{77}{x}
\]

Now, cross-multiply:

\[
7x = 77 \cdot 1
\]

This simplifies to:

\[
7x = 77
\]

Now, solve for \( x \) by dividing both sides by 7:

\[
x = \frac{77}{7} = 11
\]

So, the blank should be filled with \( 11 \). Therefore, \( 77:11 \) is equivalent to \( 7:1 \).
