Reduce fractions to lowest terms
3/8 + 1/3

So to add them use lcm (least common multiple) so 24 would be it in this case so multiply 3/8*3/3=9/24 and then 1/3*8/8=8/24 now u have denominators of 24 so u can add them, 9/24+8/24=17/24 is the answer cause it cant be reduced more

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
