Answer 1

Answer:

13. 26.73

14.360 rupees

15. 2.261

Step-by-step explanation:

13. total amount=570+315.50+210.75 = 1,096.25

amount each one contributed = 1,096.25/41

                                               = 26.73

14. 4/15 of the amount = 96

4/15×X = 96

X = 96×15/4

X = 360 rupees

15. (2÷3/5)+(3÷6/15)-(5÷7/12)

= (2×5/3)+(3×15/6)-(5×12/7)

=  (10/3)+(15/2)-(60/7)

=(20/6+45/6)-(60/7)

=(65/6)-(60/7)

= 95/42

= 2.261
