# CLASS-4SIMPLIFICATION OF DECIMAL

SIMPLIFICATION ( ADDITION AND SUBTRACTION ONLY) -

As we have learnt for simplification of whole numbers, we arrange the addition first and then subtraction. It is the same for decimal fractions too.

Principal of Simplification -

a) Convert to like decimals and then calculate.

c) For multiple subtractions, we add

1) Simplify the equation 5.88 – 4.85 – 14.4 + 28

5.88 – 4.85 – 14.4 + 28

= 5.88 + 28.00 – 4.85 – 14.4      Step.1) Convert like fraction and add

= 33.88 – (4.85 + 14.4)            Step.2) For multiple subtraction add

= 33.88 – 19.25                   Step.3) Arrange addition or subtraction

= 14.63         (Ans.)

2) Simplify the equation 85 – 8.25 – 12.48 – 15.66

85 – 8.25 – 12.48 – 15.66

= 85.00 – 8.25 - 12.48 - 15.66     Step.1) Convert like fraction and add

= 85.00 – (8.25 + 12.48 + 15.66)   Step.2) For multiple subtraction add

= 85.00 – 36.39                      Step.3) Arrange addition & subtraction

= 48.61          (Ans.)
