Answer 50

Simplify the expression.

0.625 + 3/4

Answer 51

[AI-generated answer — Bot GPT 3.5]

To simplify the expression 0.625 + 3/4, first, let's convert the decimal 0.625 to a fraction:

Now, we can rewrite the expression:

5/8 + 3/4

To add these fractions, we need a common denominator, which is 8.

We can convert 3/4 to have the same denominator:

3/4 = 6/8

Now, the expression becomes:

5/8 + 6/8

Adding the fractions:

(5 + 6)/8 = 11/8

Therefore, the simplified expression is 11/8.

Answer 52

Divide -4/17 and -3/4

Answer 53

[AI-generated answer — Bot GPT 3.5]

To divide -4/17 and -3/4, we can multiply the first fraction by the reciprocal of the second fraction:

(-4/17) / (-3/4) = (-4/17) * (4/-3)

Multiplying the numerators and denominators:

(-4 * 4) / (17 * -3) = -16 / -51

To further simplify the fraction, we can divide the numerator and denominator by their greatest common divisor (GCD), which is 1:

-16 / -51 = 16 / 51

Therefore, the result of the division -4/17 by -3/4 is 16/51.
