Answer 1

Answer:

The value of a is 36 ✔

Step-by-step explanation:

✦ Given proportion :

→ 27 : a = 63 : 84

✦ Solving for a :

→ 27 : a = 63 : 84

→ 27/a = 63/84

→ (27*84)/63 = a [transposing method]

→ 2,268/63 = a

→ 36 = a

Therefore,the value of a is 36 ✔

✦ Check point :

Substitute the value of a in the proportion :

→ 27 : 36 = 63 : 84 [∵ a = 36 ]

→ 27/36 = 63/84

→ 3/4 = 21/28 [Converting in lowest form]

→ 3/4 = 3/4

As we are getting the equal value ✔

Hence, proved ✔✔
