Question

Find the standard decimal form of:
5×
1
10
+1×
1
100

Answer 1

To convert the expression \(5 \times \frac{1}{10} + 1 \times \frac{1}{100}\) into standard decimal form, we first calculate each term separately.

1. Calculate \(5 \times \frac{1}{10}\):
\[
5 \times \frac{1}{10} = \frac{5}{10} = 0.5
\]

2. Calculate \(1 \times \frac{1}{100}\):
\[
1 \times \frac{1}{100} = \frac{1}{100} = 0.01
\]

Next, we add the two results together:
\[
0.5 + 0.01
\]

To add these, we can align them by decimal point:
```
0.50
+ 0.01
-------
```

Now, add:
```
0.50
+ 0.01
-------
0.51
```

Thus, the standard decimal form of the expression \(5 \times \frac{1}{10} + 1 \times \frac{1}{100}\) is:
\[
\boxed{0.51}
\]
