<span><span>Two numbers A & B, whose product is AB

when A increased by 30% and B decreased by 30%, the product is:
1.3A * 0.7B = 0.91AB
then
1AB - 0.91AB = 0.09 which is 9% decrease. So the answer is a 9% decrease. </span><span>

Answer:

<h3>The answer is 7/12.</h3>

Step-by-step explanation:

$( \frac{2}{3} - \frac{1}{4} ) + ( \frac{1}{2} \times \frac{1}{3} )$

Solve the terms in the bracket first

That's find the LCM of the ones which are subtracting

LCM of 3 and 4 is 12

That's

$\frac{2}{3} - \frac{1}{4} = \frac{8 - 3}{12} = \frac{5}{12}$

Next multiply the other terms in the other bracket

That's

$\frac{1}{2} \times \frac{1}{3} = \frac{1}{6}$

Add both results

That's

$\frac{5}{12} + \frac{1}{6}$

Find the LCM

The LCM is 12

We get the final answer as

$\frac{5}{12} + \frac{1}{6} = \frac{5 + 2}{12} = \frac{7}{12}$

Hope this helps you

Answer: 47.4 liters

Step-by-step explanation:

From the question, we are informed that Samuel's car usually takes about 12.5 gallons of gas to fill it up when it's empty and while in Canada, he noticed that one liter is equivalent to 0.264 gallons.

The number of liters it'll take to fill Samuels car will be:
