Write the sum of the numbers as the product of their GCF and another sum. But for 27 + 18. And put an answer that i can copy wor

Step2247 [10]

Answer: 9(3+2)

Step-by-step explanation:

The GCF of 27 and 18 is 9 because the factors of 27 are, 1,3,9 and 27 and the the factors of 18 are, 1,2,3,9 and 18.

The greatest factor that they both share is 9.

And 9 times three is 27 and 9 times 2 is 18.

This one’s pretty easy because it’s a square meaning the corners will always be 90 degrees so if a line splits the 90 it becomes half which is 45. And the reason AEB is 90 is because it’s two top corners are 45 degrees so the last angle must make the whole triangle equal 180 degrees.
DBC=45
AEB=90

4/5 + 3/4 =

The topics you should learn are equating denominators and fractions. This is summing up simple fractions.

So we have to make denominators' numbers the same in order to sum up them all (we can sum fractions if the denominators are the same) , and we did it by cross product (that thing on the picture)

Equating by lcm (least common multiple) is the easiest way, because you might see bigger numbers on other questions, and cross product will bring much bigger numbers, so this technic might confuse you.

By the way lcm of 4 and 5 is already 20

Hope it helps!
