Simplify and determine the coefficient of (-2/5)(-x)(5y)(-2x).

1 answer:

7 0

When multiplying an odd number of factors,, then that means they will equal a negative. This rule will make this expression change to the following:
- $\frac{2}{5}$ x × 5y × 2x
Now reduce the numbers with 5
-2xy × 2x
Lastly,, calculate the product to get your final answer
-4x²y
This means that your coefficient is -4 and the simplified version of your expression is -4x²y.

Ella grew 3 over 4 of an inch last year. Ben grew 2 over 3 of an inch last year. How much more did Ella grow than Ben last year?

Answer:

Ella grew $\frac{1}{12}$ of an inch more

Step-by-step explanation:

For this problem, you want to subtract Ben's growth from Ella's.

This expression would be $\frac{3}{4}$ - $\frac{2}{3}$ .

To work these out, they must have the same denominator (which should be the lowest common multiple or LCM).

In this case, the LCM is 12, so you want to multiply each side so the denominator is 12. This means the first fraction should be multiplied by $\frac{3}{3}$ and the second by $\frac{4}{4}$ .
