Isaac knows that ¼ is written as 0.25 in decimal form. How can he find a decimal for 7/5?

To find a decimal form for 7/5, Isaac can divide 7 by 5 using long division:

1. Write 7 as the dividend and 5 as the divisor: 7 ÷ 5.
2. Perform the long division.

```
1.4
________
5 │ 7.0
-5
_____
20
-20
_____
0
```

The division terminates with a quotient of 1.4. Therefore, 7/5 can be written as 1.4 in decimal form.
