Answer:
7.744
Explanation:
3.20=3.2
you can multiply just 242 and 32 then pop in the decimal point later
242*32=242*30 + 242*2
242*3*10=726*10=7260
242*2=484
7260+484=7744
2*3 (rounded version of numbers) is 6
so the answer after putting decimal point should be around 6
77.44 is way too hight
7.744 is decently close to 6
so the answer is 7.744
