Question

suppose 6 kg of salt contain 6 into 10 raise to 7 crystals how many Crystals are there in 7 kg of salt

Answer 1

if 6 Kg = 6 × 10^7 crystals
then 1 Kg = (6×10^7)/6 crystals
= 1× 10^7 crystals

So 7 Kg contains = 7×( 1×10^7) crystals

7×10^7 crystals

Answer 2

Answer:

weight=6kg , 7kg

crystals=7×10^7 , ?

=by applying direct formula

6kg × ? = 7kg × 6×10^7

= next step

? = 7kg × 6 × 10 ^7/ 6kg

( six directly cut from six )

7kg ×10^7 or 0.7×10^8

both are correct answers
