दिया गया है:

किसी संख्या का 5/6 = 675

उसी संख्या का 9/20 ज्ञात कीजिए।

प्रयुक्त सूत्र:

मान लीजिए संख्या N है।

दिए गए अनुसार, हम जानते हैं:

N × (5/6) = 675

संख्या ज्ञात करने के लिए, N = 675 ÷ (5/6)

फिर, N का 9/20 परिकलित करें: (9/20) × N

गणना:

चरण 1: N के लिए हल करें:

⇒ N = 675 ÷ (5/6)

⇒ N = 675 × (6/5)

⇒ N = 135 × 6

⇒ N = 810

चरण 2: N का 9/20 ज्ञात करें:

⇒ (9/20) × N

⇒ (9/20) × 810

⇒ 9 × 810 ÷ 20

⇒ 7290 ÷ 20

⇒ 364.5

इसलिए, संख्या के 9/20 का मान 364.5 है।
