# --description--
`/=`操作符是让变量与另一个数相除并赋值。
`myVar = myVar / 5;`
变量`myVar`等于自身除以`5`的值。等价于:
`myVar /= 5;`
# --instructions--
使用`/=`操作符实现同样的效果。
# --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(
/var a = 48;/.test(code) &&
/var b = 108;/.test(code) &&
/var 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
var a = 48;
var b = 108;
var c = 33;
// Only change code below this line
a = a / 12;
b = b / 4;
c = c / 11;
```
# --solutions--
```js
var a = 48;
var b = 108;
var c = 33;
a /= 12;
b /= 4;
c /= 11;
```
