What is the missing number in □ 15 - 9 15 = 5 15 ?

Given, □ 15 - 9 15 = 5 15 . Now, Adding 9 15 to both sides, we get, □ 15 - 9 15 + 9 15 = 5 15 + 9 15 ⇒ □ 15 = 5 15 + 9 15 ⇒ □ 15 = 5 + 9 15 ⇒ □ 15 = 14 15 Hence, the missing number is 14 .

What is the value of 2 3 + 4 5 + 4 3 + 1 5 ?

Given fractions to simplify, 2 3 + 4 5 + 4 3 + 1 5 L.C.M. of 3 and 5 = 15 2 3 = 2 × 5 3 × 5 = 10 15 4 5 = 4 × 3 5 × 3 = 12 15 4 3 = 4 × 5 3 × 5 = 20 15 1 5 = 1 × 3 5 × 3 = 3 15 Simplifying the fractions we will get 2 3 + 4 5 + 4 3 + 1 5 = 10 15 + 12 15 + 20 15 + 3 15 = 10 + 12 + 20 + 3 15 = 45 15 = 45 15 = 45 15 = 45 ÷ 5 15 ÷ 5 = 9 3 = 3 Hence, the required answer is 3 .

If 4 8 = 12 x , then what is the value of x ?

Given, 4 8 = 12 x The simplest form of 4 8 is 4 8 = 4 ÷ 4 8 ÷ 4 = 1 4 Therefore, 1 2 = 12 x Now, after cross multiplication, we get, x × 1 = 12 × 2 x = 24 Hence, the value of x is 24 .

Evaluate: 8 × 4 8 + 1 2

Given, 8 × 4 8 + 1 2 Convert the improper fractions to like fractions; L.C.M. of 8 , 2 = 8 4 8 = 4 × 1 8 × 1 = 4 8 1 2 = 1 × 4 2 × 4 = 4 8 Simplifying the fractions we will get 8 × 4 8 + 1 2 = 8 × 4 8 + 4 8 = 8 × 4 + 4 8 = 8 × 8 8 = 8 × 1 = 8 Hence, the required answer is 8 .
