Two fractions are given. For each one, write its decimal equivalent and determine if the decimal is terminating or non terminati

Answer:

9/20 yes, 4/15 not. See below

Step-by-step explanation:

Pick 9/20 and multiply numerator and denominator by 5:

9/20 = 45/100

We know that if we divide a number by 100 we need to move the coma as two places left, so:

9/20 = 45/100 = 0.45

And this is a terminal decimal as we know where it ends.

On the other hand if we pick 4/15 let try to divide it (here I will do it 'manually'):

4 |_ 15

we can divide 4 by 15, so we use 40 and begin with a comma

40 |_ 15

15 enters 2 times in 40 with a rest of 10, so:

40 |_ 15

30 0.2

100

100 divided by 15 is 6 and we have 10 as rest again, and again and again...

40 |_ 15

30 0.266.....

100

....

So, we will have 0.266666666666666 infinitely. The decimal for 4/15 is non terminating and is 0.26666666666666666...

Answer:

13 cm

Step-by-step explanation:

Use Pythagora's theorem to solve for the hypotenuse of the triangle:

$a^2+b^2=c^2$

Where a and b are the two shorter legs, and c is the hypotenuse.

Replace the values in and solve for c:

$5^2+12^2=c^2\\25+144=c^2\\169=c^2\\13=c$
