How do I compare fractions 7/10 and5/12 using benchmark

1 answer:

6 0

Answer:

first you have to find a common denominator like 60. to do this you need to multiply the first fraction by 6 and the second fraction by 5. which will give you the fractions 42/60 and 25/60. which will show you that the first fraction is greater than the second.

You can see if the other angles add up to 180 or 360 degrees (depending on shape) then add them to make it the number, for example, if a triangle has a right angle, then the other 2 angles are 45 degrees, knowing that EVERY triangle's angles add up to 180 degrees.

Answer:

Step-by-step explanation:

$using \: pythagoras \: theorem \\ let \: the \: unknown \: side = x \\ 25 {}^{2} = x {}^{2} + 20 {}^{2} \\ 625 = x {}^{2} + 400 \\ x {}^{2} = 625 - 400 \\ x {}^{2} { = 225} \\ x = \sqrt{225} \\ x = 15 \\ lenght \: of \: the \: third \: side = 15$
