1 and 2/10 * blank = 48/100

t sure would help if users just stuck to using math!!

1 and 2/10 * blank = 48/100 is so much easier to interpret if we say
1 2/10 x = 48/100
12/10 x = 48/100
x = 12/25 * 6/5 = 72/125 = 1 53/75
since we were given fractions to start with, there's no need to go to decimals

Yes, that is a valid and more simplified way to interpret and solve the equation. Thank you for providing the calculation using fractions.

0.2 * blank = 0.48

To solve for blank, we would divide both sides by 0.2:

blank = 0.48 / 0.2
blank = 2.4
