Verified Answer :

how much does she have so far in total??

2+ 3/5 is

2+\(\frac{3}{5}\)=\(2\frac{3}{5}\)

she needs 3, so she needs

3-\(2\frac{3}{5}\) more

let's change the 3 into a mixed number with a denominator of 5: \(2\frac{5}{5}\)


 \(2\frac{5}{5}\)-\(2\frac{3}{5}\)=\(\frac{2}{5}\)

so \(\frac{2}{5}\) is the answer

easy, 2+3/5=2 and 3/5
3-2 and 3/5 = 2/5

answer is 2/5
