Kara is 18 years younger than Joseph. Twelve years ago, Joseph was 4 times as old as Kara. Find their present ages.

Answers

Answer 1

Answer: Let's say x to Kara's age since Joseph is 18 years older than her, his age is x+18.
12 years ago, Kara's age was x-12 and Joseph's age was x+6. And Joseph's age was 4 times as hers. So :
$x+6=4(x-12)\n x+6=4x-48\n x+48+6=4x\n x+54=4x\n 54=4x-x\n 54=3x\n \frac { 54 }{ 3 } =x\n x=18$

Kara is 18 years old and Joseph is 18+18= 36 years old

Write 19/25 as a terminating decimal

Answers

Terminating decimals firstly are decimals that finish...
To transfer 19/25 to a decimal we have to get it out of 100.
To do this, multiply 19 by 4, and 25 by 4.
This gives you 76/100.
From here you can easily see the decimal is 0.76.

Is 25/36 in simplest form if not what is it in simplest form

Answers

The simplest form of the fraction 25/36 itself.

To simplify a fraction, we need to find the greatest common divisor (GCD) of the numerator and denominator, and then divide both by the GCD.

The GCD of 25 and 36 is 1, as there is no number other than 1 that can evenly divide both 25 and 36.

To simplify 25/36, we divide both the numerator and denominator by the GCD:

25 ÷ 1 = 25

36 ÷ 1 = 36

Therefore, the simplest form of 25/36 is still 25/36 since there is no common factor other than 1 between the numerator and denominator.

$\rm Is$ $(25)/(36)$ $\rm in\; simplest\; form\; if\; not\; what\; is\; it \;in\; simplest\; form.$

Here,

we need to check the given number is in simplest form or not?

In order to find it we first simply the given fraction,

$\rm 25=5* 5\n36=6* 6$

So, we cannot simplify it this way ,

$(25)/(36)=(5* 5)/(6 * 6)\n\n$

Therefore, 25/36 is in the simplest form itself.
