Vocabulary

numerator - the number above the fraction bar in a fraction

denominator - the number below the fraction bar in a fraction

numerator

Vocabulary Review

dividend- the number to be divided.

24 ÷ 4 = 6

divisor- the number that a dividend is divided by.

24 ÷ 4 = 6


Vocabulary review quotient the number that is the result of dividing 24 4 6 6 is the quotient

Vocabulary Review

quotient - the number that is the result of dividing.

24 ÷ 4 = 6

6 is the QUOTIENT!

Al, Lisa, Nico, and Laura are making a picture. They will share 3 rectangular strips of colored paper. What fraction represents the part of a whole strip of paper each will get?

Find 3 ÷ 4

1 whole

1 whole

1 whole


Math 5 fractions as division

One way to divide 3 wholes into 4 equal parts is to first divide each whole into 4 equal parts. Each part is ¼ of a whole.

Find 3 ÷ 4

1 whole
