Question

39_13_32_11_24=109 fill the blank with + , - , : ,* ,/​

Answer 1

Given:

• A mathematical expression  39_13_32_11_24=109 is given.

To Find:

• we have to fill the blank space by using  + , - , : ,* ,/​ to get 109 as a final answer.

Solution:

The given expression is

                          39_13_32_11_24 = 109

• First take

                          39_13   ⇒ 39 ÷ 13 = 3

• Now the expression is

                   ⇒    3_32_11_24 = 109

                           3_32    ⇒   3 ×32    = 96

Now, we get

                  ⇒      96_11_24=109

                            96_11  ⇒  96-11 = 85

Now and 85 and 24

                          ⇒85+24 = 109

Thus The final expression is      

                   39÷13×32- 11 + 24 = 109

Answer 2

$Given \: 39\_13\_32\_11\_24 = 109$

/* Using +, - , : , * , to make the Equation true , we can write like below */

$39 \red { \div } 13 \red { \times } 32 \red{ -} 11\red{+}24 = 109$

$\underline { \blue { Verification : }}$

$LHS = 39 \red { \div } 13 \red { \times } 32 \red{ -} 11\red{+}24 \\= \frac{39}{13} \red { \times } 32 \red{ -} 11\red{+}24 \\= 3 \red { \times } 32 \red{ -} 11\red{+}24 \\=96 \red{ -} 11\red{+}24 \\= 85 \red{+}24 \\= 109 \\= RHS$

Therefore.,

$39 \red { \div } 13 \red { \times } 32 \red{ -} 11\red{+}24 = 109$
