you turn 12 acres into a fraction which would be 48/4 then subtract 4 1/4 from that's because 2 2/4 + and 1 3/4 is equal to 4 1/4 you get it 2 and 2/4 by turning 2 1/2 into a fraction that has the same denominator as 1 and 3/4

First add 2 2/4 and 1 3/4
= 4 1/4
Then subtract 4 1/4 from 12
= 7 3/4

Mr. Soto plans to open a savings account. Four banks offer the annual interest rates shown. Which list shows these interest rate
Delvig [45]
Ok, so IDK if I'm about to do this problem right, but here we go;


so first, lets change these all to decimals (I more of a decimal gal)

3 1/2 = 3.5
3 2/3 = 3.6666 (repeating)
3 3/5 = 3.6
3 3/8 = 3.375

So now, just order them from greatest to least.  

3.66666, 3.6, 3.5, 3.375.  

Now, change them back to fractions.  
3 2/3, 3 3/5, 3 1/2, 3 3/8


So, if I'm correct, the answer is 3 2/3%, 3 3/5%, 3 1/2%, 3 3/8%
Hopefully I solved your problem!
