Answer:
3 is the answer
Explanation:
First convert all mixed fractions into improper fractions.
39/4 ÷ [13/6 + {13/3 - (3/2 + 7/4)}] Make the denominators same of the bold numbers. So, multiply 3/2 by 2.
= 39/4 ÷ [13/6 + {13/3 - (6/4 + 7/4)
= 39/4 ÷ [13/6 + {13/3 - 13/4}] Make the denominators same of the bold numbers. So, multiply 13/3 by 4 and 13/4 by 3.
= 39/4 ÷ [13/6 + {52/12 - 39/12}]
= 39/4 ÷ [13/6 + 13/12] Make the denominators same of the bold numbers. So, multiply 13/6 by 2.
= 39/4 ÷ [26/12 + 13/12]
= 39/4 ÷ [26+13/12]
= 39/4 ÷ 39/12 [While dividing any two rational numbers, we have to multiply the second rational number by writing its reciprocal with the first rational number]
= 39/4 × 12/39
Reduce 4 and 12 by dividing them by 4 and you will get 1 and 3 respectively. Cut 39 in both the places as they are same.
So, now you will get 1/1 × 3/1
= 3/1 that is 3.
Hope this helps you...
