40%*2=80 I hope I helped!
Answer: is 3a + b/5 if the equation is 1/5(15a+b) and is 75a+5b if it is 1*5(15a+b) I couldn’t tell if the 1 and 5 were a fraction or being multiplied.
You can change them into fractions with the same denominator: multiply 3/4 by 3 and 2/3 by 4
3/4 = 9/12
2/3 = 8/12
You could also convert them to decimals.
3/4 = 0.75
2/3 = 0.667
3/4 is greater than 2/3
0.6 milliliters
(I'm not 100% positive, you might have to convert it...but it seems correct.)
Then you better turn it in soon!
