Question

Find the value for ? to make the equation true. Enter the answer in the box.
28/100= ?/10 + 8/100

Answer 1

To solve the equation \( \frac{28}{100} = \frac{?}{10} + \frac{8}{100} \), we can first simplify the equation.

Start by subtracting \( \frac{8}{100} \) from both sides:

\[
\frac{28}{100} - \frac{8}{100} = \frac{?}{10}
\]

Now combine the fractions on the left side:

\[
\frac{28 - 8}{100} = \frac{?}{10}
\]

This simplifies to:

\[
\frac{20}{100} = \frac{?}{10}
\]

Next, simplify \( \frac{20}{100} \):

\[
\frac{20}{100} = \frac{1}{5}
\]

Now we have:

\[
\frac{1}{5} = \frac{?}{10}
\]

We can cross-multiply to solve for \( ? \):

\[
1 \times 10 = 5 \times ?
\]

This gives:

\[
10 = 5?
\]

Dividing both sides by 5:

\[
? = \frac{10}{5} = 2
\]

Thus, the value for \( ? \) is \( \boxed{2} \).
