What percent of 72 is 48 with step by step process
Sedaia [141]

Answer:

67%

Step-by-step explanation:

There are a few methods to finding the percent of a number.  You can use proportions:

\frac{percent}{100}=\frac{48}{72}

The 'percent' is the percent of the fraction that you are looking for, or 48/72.

Cross-multiply:  72x = (48)(100) or 72x = 4800

Divide both sides by 72:  72x/72 = 4800/72

Solve for 'x':  x = 66.6666...

Round 66.666.... to the nearest percent: 67%

vitfil [10]

Answer:

-20

Step-by-step explanation:

First, you divide both sides by -2/5, which would get you c = 8 * -5/2 (Because when you divide, you multiply by the reciprocal). 8 * -5/2 is equal to -20. The answer is -20.

A water tank is 3/4 full.
guapka [62]

x/.75=x-56/0.4

0.4x=.75x-42

-0.35x=-42

x=120

I set up a proportion in which x=the tank when it is 3/4 full. When the tank is 3/4 full, solving the proportion tells us the x=120 litres. 120/3=40, and 120+40 is 160, showing that a tank completely full would indeed hold 160 litres.

Hope this helps!
