Answer 1

Step-by-step explanation:

One 5 rupee coin weighs 9grams

So,

(a). x coins weigh 19kg=19000g

when we cross multiply:

19000=9x

19000/9=x

x=2111.1111 coins which is recurring so approximately it is

2111 coins.

(b). using the same concept:64kg= 64000g

64000/9=x

x=7111.111

approx=7111 coins
