Answer:

434

2021

Step-by-step explanation:

• In mathematics, a multiplicative inverse or reciprocal for a number x, denoted by 1/x or x⁻¹, is a number which when multiplied by x yields the multiplicative identity, 1. The multiplicative inverse of a fraction a/b is b/a. For the multiplicative inverse of a real number, divide 1 by the number.

In terms of examples,

• RECIPROCAL OF 39 = 1/39 (BECAUSE, a whole number always ends with denominator 1.)
• RECIPROCAL OF 24/4 = 4/24
• RECIPROCAL OF 39/36 = 36/39

So, the reciprocal of 47/9

= 9/47

Similarly, the reciprocal of 43

= 1/43

9/47 + 1/43

(Both 47 and 43 are prime numbers. They do not have a LCM. By multiplying 47 × 43, we get 2021.)

= 387 + 47

2021

= 434
