Answer» Rules of Approximation: 1. If a number has digits to the right of the decimal LESS than 5, then just drop the digits to the right of the decimal. The number HENCE obtained will be the approximated value. 2. If a number has digits to the right of the decimal more than 5, then just drop the digits to the right of the decimal and RAISE the remaining number by '1'.The number hence obtained will be the approximated value. Using the same approach we will solve the given expression: 5432.8777 − 3185.992 − 2141.685 + 4876.418 ÷ 203.184 = 5433 − 3186 − 2142 + 4876 ÷ 203 = (5433 + 24) − (3186 + 2142) = 5457 − 5328 = 129

Rules of Approximation:

1. If a number has digits to the right of the decimal LESS than 5, then just drop the digits to the right of the decimal. The number HENCE obtained will be the approximated value.

2. If a number has digits to the right of the decimal more than 5, then just drop the digits to the right of the decimal and RAISE the remaining number by '1'.The number hence obtained will be the approximated value.

Using the same approach we will solve the given expression:

5432.8777 − 3185.992 − 2141.685 + 4876.418 ÷ 203.184

= 5433 − 3186 − 2142 + 4876 ÷ 203

= (5433 + 24) − (3186 + 2142)

= 5457 − 5328

= 129
