Answer:
a*b = 1/2
a/ b = 8/9
Step-by-step explanation:
a = 0.66666 and b = 0.75
To multiply it we write the decimal numbers in fraction form
a= 0.666666...
Multiply by 10 on both sides
10 a = 6.66666...
a = 0.66666...
Subtract the second equation
9a = 6
divide by 9 on both sides

so 0.6666 = 2/3
Now we convert 0.75 into fraction form

Multiply top and bottom by 100 to remove decimal

so 0.75 is 3/4
a= 2/3 and b = 3/4


Step-by-step explanation:
16+5.6+0.681=22.281

If I'm correct you should make a fraction first
5.4 3.6
----- to -----
4.8 ?
Now find the missing number
5.4 to 3.6 would be a difference of ÷ 1.5 so you must do the same for 4.8
