Question

What is `\frac{7}{8} ( - 2\cdot \frac{2}{5} )`?

Answer 1

`-7/10`

Explanation:

Because of the Order of Operations, we always solve the part inside the parentheses first. `-2` is equal to `-2/1`, so we can multiply`-2/1 * 2/5` This leaves us with `7/8(-4/5)` Now all that needs to be done is multiplication.

Just multiply `7*-4` and `8*5`. This gives you `-28` and `40`.

Don't forget that you were multiplying fractions . These numbers must be returned to their fraction form, `-28/40`

Finally, fractions should always be put in simplest terms. `-28` and `40` can both be divided by `4`. Doing this gives you the desired answer of `-7/10`
