Question

Find the product (4/5)(9/5)(-1/2) a) -18/25 b)-25/18 c)18/25 d)8/25

Answer 1

Answer:

The answer is A, -18/25.

Step-by-step explanation:

Step 1 : Multiply the first part (4/5 and 9/5).

$\frac{4}{5}$ · $\frac{9}{5}$ = $\frac{36}{25}$

Step 2 : Multiply $\frac{36}{25}$ with -$\frac{1}{2}$.

$\frac{36}{25}$ · $\frac{-1}{2}$ = $\frac{18}{25}$ · $\frac{-1}{1}$ (Since we can divide by 2 with the 36 and the 2.)

$\frac{18}{25}$ · $\frac{-1}{1}$ = $\frac{-18}{25}$

Therefore the answer is A, -18/25.

Answer 2

Answer:

A) -18/25

Step-by-step explanation:

4/5 times 9/5 times -1/2.

First multiply the numerators which equals (4)(9)(-1) = -36, then the denominators together which equals (5)(5)(2)= 50. Together the numerator and denominator becomes a fraction of -36/50. You simplify this by dividing the numerator and denominator by 2, because it is a factor of both numbers. This will then equal -18/25
