The Sum Of Two Rational Numbers Is 7(2/3). If One Of The Numbers Is 3(1/6) Find The Order Number

Answer 1

other*

ATQ, the sum of two rational number is 7⅔ and one of the no. is 3 1/6

we have to find the other no.

so first of all, we needa convert the mixed fraction in proper fraction.

• 7⅔ = [(3 × 7) + 2]/3 = 23/3

• 3 ¹/6 = [(6 × 3) + 1]/6 = 19/6

now, let us take the other no. as x

therefore 19/6 + x = 23/6

➡ x = 23/3 - 19/6

LCM of 3 and 6 = 3 × 2 = 6

➡ x = (23 × 2)/(3 × 2) - 19/6

➡ x = 46/6 - 19/6

➡ x = 27/6 = (3 × 3 × 3)/(2 × 3)

➡ x = 9/2

or x = 4½

hence the other no. is 4½

Answer 2

Step-by-step explanation:

let other no. be x, then

x+3(1/6) = 7(2/3)

x+19/6 = 23/3

x = 23/3 - 19/6

x = 46 - 19 / 6 ( by taking LCM)

x = 27/6

x = 9/2

x = 4(1/2)

hence other no. is 4(1/2)
