Question

what is the top and bottom called on a fraction


and what is a common denominator

Answer 1

Answer:

A fraction is in two parts. The top number is called the numerator and the bottom number is called the denominator. The top number (numerator) is the whole thing that is to be broken up. The bottom number (denominator) is how many equal parts it has been broken into.

Answer 2

~ Top of the fraction is called Numerator

~ Bottom of the fraction is called Denominator

~ We can obtain common denominators by multiplying both numerator (top) and denominator (bottom) by the same amount.

~ Addition of 2⁄5 and 1⁄2 .

# First, multiply 2⁄5 by 2⁄2 to get 4⁄10 .

# Now multiply the second fraction 1⁄2 by 5⁄5 to get 5⁄10 .

# The new fractions have a common denominator 10.

# Add the two fractions 4⁄10 + 5⁄10 to get 9⁄10

( Trick - The lowest common multiple of the denominators helps us obtain common denominator )

Hope it helps you..!!!
