2 1/2 x 1 1/2

First, make them both improper fractions to make them easier to multiply

5/2 x 3/2

Multiply their numerators together to get the numerator and multiply their denominators together to get the denominator.

5 x 3 = 15

2 x 2 = 4

V / -0.8 +14=39 plssss help this is literally so hard

Nat2105 [25]

<h2><u>Answer:</u></h2><h2> $\boxed{\boxed{\sf~v=-20}}$ </h2><h2 /><h2><u>Solution Steps:</u></h2>

______________________________

<h3>1.) Subtract 14 from both sides:</h3>

$14-14=$ Cancels Out

$39-14=25$

<em> - We do this because we have to get 2 variables/numbers on each side of the equals, and the only way to do so is to cancels other numbers out by doing the opposite of what we see. </em>

<u>Equation at the end of Step 1: </u>

$v$ ÷ $-0.8=25$

<h3>2.) Multiply both sides by −0.8:</h3>

$-0.8$ × $-0.8=$ Cancels Out

$25$ × $-0.8=-20$
