# --description--
`/=` 操作符是讓變量與另一個數相除並賦值。
```js
myVar = myVar / 5;
```
`myVar` 除以 `5`。 等價於:
```js
myVar /= 5;
```
# --instructions--
使用 `/=` 操作符對 `a``b``c` 實現相除賦值操作。
# --hints--
`a` 應該等於 `4`
```js
assert(a === 4);
```
`b` 應該等於 `27`
```js
assert(b === 27);
```
`c` 應該等於`3`
```js
assert(c === 3);
```
應該對每個變量使用 `/=` 操作符。
```js
assert(code.match(/\/=/g).length === 3);
```
不要修改註釋上面的代碼。
```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;
```
