Find the missing number: 2016 · 199 = 2016·? +2016 · 98 Pls tell how you did it as well

Alex Ar [27]

Answer:

101

Step-by-step explanation:

Given the expression:

2016 · 199 = 2016·? +2016 · 98

We could rewrite the expression such that the missing value equals x

2016 * 199 = 2016 * x + 2016 * 98

Using BODMAS:

401184 = 2016x + 197568

401184 - 197568 = 2016x

203616 = 2016x

Divide both sides by 2016

203616 / 2016 = 2016x / 2016

101 = x

Hence, missing value is 101
