Answer 2

Answer:

6)  3:7          7)     6:5

Step-by-step explanation:

6) number of days in 3 weeks = 3 x 7 = 21

   so ratio = 9 : 21  which when simplified is 3 : 7  (c)

7)   MATHEMATICS has 11 words

    from which 6 are consonants which are M, T , H , M , T , C, S

    and the rest of the words will be vowels ( 11 - 6 = 5)

so the ratio = 6 : 5  (d)
