Explanation:
Some of the numbers are REALLY hard to read. Please check that I used the right numbers.
7) Is that 2/3 or 2/5? I think it’s 2/5. If so, 2/5x4/5=8/25
11) 3/4÷1/6=3/4x6/1=18/4=9/2
13) 3/8+1/5=15/40+8/40=23/40
17) 1 3/4x2/3=7/4x2/3=14/12=7/6 or 1 1/6
19) 3 1/2+2 3/5=7/2+13/5=35/10+26/10=61/10
