If b was 3 a will be 6 because 2*3=6
and for the second part b will be 3.5 because 2*3.5=7
25/100 = 1/4 (divide both numerator and denominator by 25)
350/1000 = 35/100 = 7/20.
6.9 = 6.9 / 1
Numerator = 6.9 × 10 = 69
Denominator = 1 × 10 = 10
Numerator / Denominator = 69 / 10
Simplifying our fraction
= 69/10
= 69/10
= 6 9/10
Using the formula then calculator to get the ans and we must never forget to write the unit in squared form.
