Write as a single fraction a 4 + 2 a 4

Given that, a 4 + 2 a 4 We know that, When denominator of fractions are same we add or subtract the numerators, Thus, a 4 + 2 a 4 = a + 2 a 4 = 3 a 4 Hence, a 4 + 2 a 4 = 3 a 4

Write as a single fraction a 4 + 2 a 4

Given that, a 4 + 2 a 4 We know that, When denominator of fractions are same we add or subtract the numerators, Thus, a 4 + 2 a 4 = a + 2 a 4 = 3 a 4 Hence, a 4 + 2 a 4 = 3 a 4

Write as a single fraction 4 b 5 - 2 b 5

Given that, 4 b 5 - 2 b 5 We know that, When denominator of fractions are same we add or subtract the numerators, Thus, 4 b 5 - 2 b 5 = 4 b - 2 b 5 = 2 b 5 Hence, 4 b 5 - 2 b 5 = 2 b 5

Write as a single fraction c 3 + d 3

Given that, c 3 + d 3 We know that, When denominator of fractions are same we add or subtract the numerators, Thus, c 3 + d 3 = c + d 3 Hence, c 3 + d 3 = c + d 3

Write as a single fraction 3 y 6 - y 6

Given that, 3 y 6 - y 6 We know that, When denominator of fractions are same we add or subtract the numerators, Thus, 3 y 6 - y 6 = 3 y - y 6 = 2 y 6 = y 3 Hence, 3 y 6 - y 6 = y 3

Write as a single fraction x 2 + x 4

Given that, x 2 + x 4 We know that, When denominators of the fractions are not same,then take L . C . M of denominator to make them, x 2 + x 4 L . C . M 2 , 4 = 4 x 2 + x 4 = 2 x + x 4 = 3 x 4 Hence, x 2 + x 4 = 3 x 4

Write as a single fraction 2 y 3 + y 6

Given that, 2 y 3 + y 6 We know that, When denominators of the fractions are not same,then take L . C . M of denominator to make them, 2 y 3 + y 6 L . C . M 3 , 6 = 6 2 y 3 + y 6 = 4 y + y 6 = 5 y 6 Hence, 2 y 3 + y 6 = 5 y 6

Write as a single fraction 2 b 5 - b 4

Given that, 2 b 5 - b 4 We know that, When denominators of the fractions are not same,then take L . C . M of denominator to make them equal, 2 b 5 - b 4 L . C . M 5 , 4 = 20 2 b 5 - b 4 = 8 b - 5 b 20 = 3 b 20 Hence, 2 b 5 - b 4 = 3 b 20

Write as a single fraction x 2 + y 3

Given that, x 2 + y 3 We know that, When denominators of the fractions are not same,then take L . C . M of denominator to make them, x 2 + y 3 L . C . M 2 , 3 = 6 x 2 + y 3 = 3 x + 2 y 6 Hence, x 2 + y 3 = 3 x + 2 y 6

Write as a single fraction 3 x 5 - x 6

Given that, 3 x 5 - x 6 We know that, When denominators of the fractions are not same,then take L . C . M of denominator to make them, 3 x 5 - x 6 L . C . M 5 , 6 = 30 3 x 5 - x 6 = 18 x - 5 x 30 = 13 x 30 Hence, 3 x 5 - x 6 = 13 x 30
