2.33 inches and 4.66 inches
2x+x=7 or 3x=7
divide by three and x =2.33
that's for the first one and the second one is twice the size so it'll be 4.66 inches
to find this, we need to convert again. use the fact that a b/c = (ac + b) / c, to get 3/2 over 10/3. multiply by the lcm (least common multiple) which is what it sounds like. : p
so, if you skip count, the least common multiple is 6, so you multiply by 6 on both sides to get 9/20.
