Question

Plz answer Qn no 2 and 3​

Answer 1

Answer:

Answer of Q 2 is 140

Answer of Q 3 is - 2/5 or (5/-2)^-1

Step-by-step explanation:

FOR Q2

• Suppose a nunber x
• Now according to the question the 3/5 x exceeds than 2/7x by 44
• So equation will be 3/5x = 2/7x + 44

FOR Q3

• Let a nunber be x
• Take reciprocal to turn power to positive

Answer 2

Answer:

2) The required number is 140

3) The required number is -2/5

Step-by-step explanation:

2)

Let x be the required number

3x/5-2x/7 = 44

(21x-10x )/35 = 44

11x = 35 x 44

x = 35x4

= 140

3) (-5/4)⁻¹ = -4/5

(1/2)⁻¹ = 2

Let x be the required number

dividend = divisor x quotient + remainder

x = (- 4/5)/2 = - 2/5
