Answer 1

Answer:15. b)3.15

16. C)0.005983kg

Step-by-step Explanation:

15) donates blood 3 times in 2 years, therefore in next two years again 3 times and in next two years again 3 times. Hence total of time’s = 3+3+3=9times in 6 years

350ml———->1 time

? ———->9

9*350=3150ml

1 litre = 1000ml

? = 3150ml

I.e., 3150/1000 = 3.15Litre

16) 1kg ————> 1000000mg

? ————> 5983mg

5983/1000000 = 0.005983kg(since the denominator has six 0’s the decimal in the numerator is shifted to left by six)
