# --description--

`/=` 操作符是让变量与另一个数相除并赋值。

```js
myVar = myVar / 5;
```

将 `myVar` 除以 `5`。 等价于：

```js
myVar /= 5;
```

# --instructions--

使用 `/=` 操作符对 `a`，`b` 和 `c` 实现相除赋值操作。

# --hints--

`a` 应该等于 `4`。

```js
assert(a === 4);
```

`b` 应该等于 `27`。

```js
assert(b === 27);
```

`c` 应该等于`3`。

```js
assert(c === 3);
```

应该对每个变量使用 `/=` 操作符。

```js
assert(code.match(/\/=/g).length === 3);
```

不要修改注释上面的代码。

```js
assert(
  /let a = 48;/.test(code) &&
    /let b = 108;/.test(code) &&
    /let c = 33;/.test(code)
);
```

# --seed--

## --after-user-code--

```js
(function(a,b,c){ return "a = " + a + ", b = " + b + ", c = " + c; })(a,b,c);
```

## --seed-contents--

```js
let a = 48;
let b = 108;
let c = 33;

// Only change code below this line
a = a / 12;
b = b / 4;
c = c / 11;
```

# --solutions--

```js
let a = 48;
let b = 108;
let c = 33;

a /= 12;
b /= 4;
c /= 11;
```
