What is the product of -3/8 + -4/12 simplfy your answer

Snezhnost [94]

Answer:

$-\frac{17}{24}$

Step-by-step explanation:

First we need to find the common denominator of 8 and 12, which is 24.

Next we rewrite our fractions:

$-\frac{9}{24} - \frac{8}{24} = -\frac{17}{24}$

This cannot be reduced.

Option B

$\frac{a^2b^7c^2}{a^2c^2} = b^7$

Solution:

Given that, we have to simplify the given expression

Given expression is:

$\frac{a^2b^7c^2}{a^2c^2}$

We can simplify the expression by cancelling the common terms in numerator and denominator

Take the common terms out in given expression

$\frac{a^2b^7c^2}{a^2c^2} = \frac{a^2c^2(b^7)}{a^2c^2}$

Cancel the common terms in numerator and denominator

$\frac{a^2b^7c^2}{a^2c^2} = \frac{a^2c^2(b^7)}{a^2c^2} = b^7$

Thus the simplified form of given expression:

$\frac{a^2b^7c^2}{a^2c^2}=b^7$

Thus option B is correct
