Find the percent of change. 120lbs to 1801bs

mart [117]

Quick Note: I'm pretty sure you meant 180LBS and not 1801bs, so I'm using 180, but if it was 1801 please tell me

Percent of change = $\frac{V2 - V1}{V1} *100$

Substitute 180 for V2 and 160 for V1
Percent of change = $\frac{180-160}{160} * 100$

Solve
Percent of change = $\frac{20}{160} *100$
Percent of change = 0.125 x 100
Percent of change = 12.5%

kati45 [8]

Answer:

19/24 = 0.791666667

Step-by-step explanation:

Since 21/24 and 2/24 have the same denominator, subtract them by subtracting their numerators.

21 - 2 / 24

Subtract 2 from 21 to get 19.
