Convert 2 4 , 6 8 , 7 12 and 12 16 into like fractions.

The given fractions are 2 4 , 6 8 , 7 12 and 12 16 . L . C . M . of 4 , 8 , 12 and 16 = ( 2 × 2 × 2 × 2 × 3 ) = 48 So, we convert the given fractions into equivalent fractions with 48 as the denominator. Thus, 2 4 = 2 × 12 4 × 12 = 24 48 ; 6 8 = 6 × 6 8 × 6 = 36 48 ; 7 12 = 7 × 4 12 × 4 = 28 48 ; 12 16 = 12 × 3 16 × 3 = 36 48 Hence, the required like fractions are 24 48 , 36 48 , 28 48 and 36 48 .

Convert into like fractions 3 4 and 2 3

Like fractions are fractions having the same denominators. We have to convert 3 4 and 2 3 into like fractions. Find the LCM of the denominators of the fractions. So, LCM of 4 and 3 is 12 . Multiply the numerator and denominator of a fraction by a number such that the denominator equalizes with the LCM. 3 × 3 4 × 3 = 9 12 2 × 4 3 × 4 = 8 12 Thus, the like fractions are 9 12 and 8 12 .

Convert into like fractions 5 6 and 3 4

Like fractions are fractions having the same denominators. We have to convert 5 6 and 3 4 into like fractions. Find the LCM of the denominators of the fractions. So, LCM of 6 and 4 is 12 . Multiply the numerator and denominator of a fraction by a number such that the denominator equalizes with the LCM. 5 × 2 6 × 2 = 10 12 3 × 3 4 × 3 = 9 12 Thus, the like fractions are 10 12 and 9 12 .

Convert into like fractions 1 5 and 5 6

Like fractions are fractions having the same denominators. We have to convert 1 5 and 5 6 into like fractions. Find the LCM of the denominators of the fractions. So, LCM of 5 and 6 is 30 . Multiply the numerator and denominator of a fraction by a number such that the denominator equalizes with the LCM. 1 × 6 5 × 6 = 6 30 5 × 5 6 × 5 = 25 30 Thus, the like fractions are 6 30 and 25 30 .

Write the missing terms of the equivalent fractions: 40 50 = 4 □ = □ 10 = □ 25 = 80 □ = 120 □

We need to find the missing terms of the equivalent fractions: 40 50 = 4 □ = □ 10 = □ 25 = 80 □ = 120 □ Equivalent fractions represent the same part of a whole. To find an equivalent fraction, we may multiply or divide the numerator and the denominator of the given fraction by the same number. 40 50 = 4 □ ⇒ 40 50 = 40 ÷ 10 50 ÷ 10 = 4 5 4 5 = □ 10 ⇒ 4 5 = 4 × 2 5 × 2 = 8 10 4 5 = □ 25 ⇒ 4 5 = 4 × 5 5 × 5 = 20 25 4 5 = 80 □ ⇒ 4 5 = 4 × 20 5 × 20 = 80 100 4 5 = 120 □ ⇒ 4 5 = 4 × 30 5 × 30 = 120 150 Thus, we can write the missing terms of the equivalent fractions as 40 50 = 4 5 = 8 10 = 20 25 = 80 100 = 120 150 .
