Easy simplification questions for class 5 with answers and practice questions

Simplification questions for class 5

To  simplify a numerical expression having two or more operations, we use ‘BODMAS’  , where the letters  B, O, D, M,  A,  S stand for Brackets , orders(powers/indices or roots) ,  Division,  Multiplication,  Addition  and  Subtraction  respectively. The following questions  on simplifications has different types of questions that can be practiced by the students to get more ideas to simplify the expressions.

Simplification questions for class 5 (solved examples)

(i) 14 x 7+36÷4+14

sol.  14 x 7+36÷4+14= 14 x 7+9 +14                         (performing division )

= 98+9+14                                  (performing multiplication)

=121

(ii) 100-56÷7+15 x 2

Sol. 100-56÷7+15 x 2= 100-8+15 x 2     (simplifying  division)

= 100-8+30           ( simplifying  multiplication) 

= 100+30-8

= 130-8 = 122

(ii)  19  [4 + {16  (12  2)}]

Sol.  19 – [4 + {16 – (12 – 2)}] = 19 – [4 + {16 – 10}]                        (Removing  small brackets)

= 19 – [4 + 6]                                    (Removing curly  brackets)

= 19 – 10                                           (Removing square brackets)

= 9

(iv ) 12-[20 ÷{8-2(9-5-2)}]

Sol. 12-[20 ÷{8-2(9-5-2)}]= 12-[20 ÷{8-2 x 2}]                 (removing small brackets)

=12-[20 ÷{8-4}]

=12-[20 ÷4]                                  (removing braces)

= 12-5                                             (removing big brackets)

=7

(v) [24 ÷ {10- (8- \overline{6-2}

)}]

Sol. [24 ÷ {10- (8- \overline{6-2})}] = [24 ÷ {10- (8- 4)}]                  (removing bar)

=[24 ÷ {10- 4}]                           (removing small brackets)

=[24 ÷ 6]                                      (removing braces)

=4                                                    (removing big brackets)
